Question 1
Harry walks from an initial position of x = -12 m to a final position of x = -47 m. If this journey
takes him 35 seconds, what is his average velocity?
A) -1.5 m/s
B) -1.0 m/s
C) 1.0 m/s
D) -35 m/s
E) -0.5 m/s
Correct Answer: B) -1.0 m/s
Rationale: Velocity is defined as the change in position (displacement) divided by the time
interval. Displacement Δ𝑥 = 𝑥𝑓 − 𝑥𝑖 = −47 m − (−12 m) = −35 m. Velocity 𝑣 = Δ𝑥/Δ𝑡 =
−35 m/35 s = −1.0 m/s.
Question 2
In a city with a square grid where each block is 135 m long, you drive north for three blocks and
then west for two blocks. How far are you from your starting point (straight-line distance)?
A) 675.00 m
B) 405.00 m
C) 486.75 m
D) 520.25 m
E) 135.00 m
Correct Answer: C) 486.75 m
Rationale: This is a Pythagorean theorem problem (𝑎2 + 𝑏 2 = 𝑐 2 ). The northward distance
is 3 × 135 = 405 m. The westward distance is 2 × 135 = 270 m. The distance 𝑑 =
√4052 + 2702 = √164025 + 72900 = √236925 ≈ 486.75 m.
Question 3
A major league pitcher throws a 95 mph fastball. If the pitcher's mound is 60 feet from the batter,
how much time elapses from the moment the ball leaves the hand until it reaches the batter?
A) 0.55 s
B) 0.38 s
C) 0.43 s
D) 0.60 s
E) 0.47 s
Correct Answer: C) 0.43 s
Rationale: First, convert 95 mph to feet per second: 95 × 1.467 = 139.36 ft/s. Using the
formula 𝑡 = 𝑑/𝑣: 𝑡 = 60 ft/139.36 ft/s ≈ 0.43 s.
Question 4
A cross-country skier is traveling at 8.0 m/s. She stops pushing and glides, slowing to 6.0 m/s
, 2
after a distance of 5.0 m. What is the magnitude of her acceleration?
A) 2.0 m/s²
B) 2.8 m/s²
C) 5.0 m/s²
D) 1.4 m/s²
E) 0.8 m/s²
Correct Answer: B) 2.8 m/s²
Rationale: Use the kinematic equation 𝑣𝑓2 = 𝑣𝑖2 + 2𝑎𝑑. Rearranging for 𝑎: 𝑎 = (𝑣𝑓2 −
𝑣𝑖2 )/2𝑑. 𝑎 = (62 − 82 )/(2 × 5) = (36 − 64)/10 = −2.8 m/s2. The magnitude is 2.8 m/s².
Question 5
To leap straight up to a height of 110 cm, with what minimum speed must a person leave the
ground?
A) 3.25 m/s
B) 5.10 m/s
C) 4.64 m/s
D) 9.80 m/s
E) 2.15 m/s
Correct Answer: C) 4.64 m/s
Rationale: Use 𝑣𝑓2 = 𝑣𝑖2 + 2𝑔ℎ. At the peak, 𝑣𝑓 = 0. Height ℎ = 1.10 m and 𝑔 =
−9.8 m/s2 . 0 = 𝑣𝑖2 + 2(−9.8)(1.10) ⇒ 𝑣𝑖2 = 21.56 ⇒ 𝑣𝑖 = √21.56 ≈ 4.64 m/s.
Question 6
A pipe 2.5 m above a creek discharges water horizontally at 1.5 m/s. How far horizontally from
the end of the pipe does the water hit the creek?
A) 0.71 m
B) 1.07 m
C) 2.50 m
D) 1.50 m
E) 0.55 m
Correct Answer: B) 1.07 m
Rationale: First, find the time to fall:
𝑡 = √2ℎ/𝑔 = √5.0/9.8 ≈ 0.714 s
. Then, find the horizontal distance:
𝑥 = 𝑣𝑥 × 𝑡 = 1.5 m/s × 0.714 s ≈ 1.07 m

Question 7
A Scion iQ drives in a circle 8.0 m in diameter at a speed of 5 m/s. What is the magnitude of the
car's centripetal acceleration?
A) 3.13 m/s²
B) 1.56 m/s²
C) 6.25 m/s²
D) 12.50 m/s²
E) 0.63 m/s²
Correct Answer: C) 6.25 m/s²
Rationale: Centripetal acceleration 𝑎 = 𝑣 2 /𝑟
. The diameter is 8.0 m, so the radius 𝑟 = 4.0 m
. 𝑎 = 52 /4 = 25/4 = 6.25 m/s2
.
Question 8
Why is an infant safer in a rear-facing child safety seat during a head-on collision?
A) The seat belt is tighter in that position.
B) Airbags do not reach the back of the car.
C) The padded back of the seat supports the head and back, spreading the force over time and
preventing whiplash.
D) The infant is further away from the engine.
E) Gravity pulls the infant downward into the seat.
Correct Answer: C) The padded back of the seat supports the head and back, spreading the
force over time and preventing whiplash.
Rationale: In a head-on collision, the car stops abruptly, but the child continues forward. A
rear-facing seat uses its entire structure to support the child's heavy head and fragile neck,
distributing the impact force over a larger area and a longer time interval.
Question 9
A spider is motionless, suspended from a single strand of silk attached to the ceiling. Which
forces are acting on the spider?
A) Tension and Friction
B) Weight and Normal Force
C) Tension and Weight
D) Weight and Air Resistance
E) Centripetal Force and Weight
Correct Answer: C) Tension and Weight
Rationale: Since the spider is motionless (static equilibrium), the downward force of gravity
(Weight) is perfectly balanced by the upward force exerted by the silk strand (Tension).

Question 10
A 1500 kg car travels at 20 m/s. Two seconds later, its speed is 21 m/s. What is the magnitude of
the net force acting on the car?
A) 1500 N
B) 750 N
C) 3000 N
D) 500 N
E) 100 N
Correct Answer: B) 750 N
Rationale: First, find acceleration:
𝑎 = Δ𝑣/Δ𝑡 = (21 − 20)/2 = 0.5 m/s2
. Then, use Newton's Second Law:
𝐹𝑛𝑒𝑡 = 𝑚𝑎 = 1500 kg × 0.5 m/s2 = 750 N
.
Question 11
A girder is being lifted at a constant speed by a crane. In what state of equilibrium is the girder?
A) Static Equilibrium
B) Dynamic Equilibrium
C) Unstable Equilibrium
D) Not in equilibrium
E) Rotational Equilibrium only
Correct Answer: B) Dynamic Equilibrium
Rationale: Equilibrium occurs when the net force is zero. If an object is moving at a
constant speed in a straight line, it is in dynamic equilibrium because its acceleration is
zero.
Question 12
You are holding a box by squeezing the sides (applying horizontal force). What specific force is
responsible for preventing the box from falling (the force opposite the weight)?
A) Normal force
B) Squeezing force
C) Kinetic friction
D) Static friction
E) Tension
Correct Answer: D) Static friction
Rationale: When you squeeze the box, you create a normal force against the sides. This

Question 1
Harry walks from an initial position of x = -12 m to a final position of x = -47 m. If this journey
takes him 35 seconds, what is his average velocity?
A) -1.5 m/s
B) -1.0 m/s
C) 1.0 m/s
D) -35 m/s
E) -0.5 m/s
Correct Answer: B) -1.0 m/s
Rationale: Velocity is defined as the change in position (displacement) divided by the time
interval. Displacement Δ𝑥 = 𝑥𝑓 − 𝑥𝑖 = −47 m − (−12 m) = −35 m. Velocity 𝑣 = Δ𝑥/Δ𝑡 =
−35 m/35 s = −1.0 m/s.
Question 2
In a city with a square grid where each block is 135 m long, you drive north for three blocks and
then west for two blocks. How far are you from your starting point (straight-line distance)?
A) 675.00 m
B) 405.00 m
C) 486.75 m
D) 520.25 m
E) 135.00 m
Correct Answer: C) 486.75 m
Rationale: This is a Pythagorean theorem problem (𝑎2 + 𝑏 2 = 𝑐 2 ). The northward distance
is 3 × 135 = 405 m. The westward distance is 2 × 135 = 270 m. The distance 𝑑 =
√4052 + 2702 = √164025 + 72900 = √236925 ≈ 486.75 m.
Question 3
A major league pitcher throws a 95 mph fastball. If the pitcher's mound is 60 feet from the batter,
how much time elapses from the moment the ball leaves the hand until it reaches the batter?
A) 0.55 s
B) 0.38 s
C) 0.43 s
D) 0.60 s
E) 0.47 s
Correct Answer: C) 0.43 s
Rationale: First, convert 95 mph to feet per second: 95 × 1.467 = 139.36 ft/s. Using the
formula 𝑡 = 𝑑/𝑣: 𝑡 = 60 ft/139.36 ft/s ≈ 0.43 s.

A) 2.0 m/s²
B) 2.8 m/s²
C) 5.0 m/s²
D) 1.4 m/s²
E) 0.8 m/s²
Correct Answer: B) 2.8 m/s²
Rationale: Use the kinematic equation 𝑣𝑓2 = 𝑣𝑖2 + 2𝑎𝑑. Rearranging for 𝑎: 𝑎 = (𝑣𝑓2 −
𝑣𝑖2 )/2𝑑. 𝑎 = (62 − 82 )/(2 × 5) = (36 − 64)/10 = −2.8 m/s2. The magnitude is 2.8 m/s².
Question 5
To leap straight up to a height of 110 cm, with what minimum speed must a person leave the
ground?
A) 3.25 m/s
B) 5.10 m/s
C) 4.64 m/s
D) 9.80 m/s
E) 2.15 m/s
Correct Answer: C) 4.64 m/s
Rationale: Use 𝑣𝑓2 = 𝑣𝑖2 + 2𝑔ℎ. At the peak, 𝑣𝑓 = 0. Height ℎ = 1.10 m and 𝑔 =
−9.8 m/s2 . 0 = 𝑣𝑖2 + 2(−9.8)(1.10) ⇒ 𝑣𝑖2 = 21.56 ⇒ 𝑣𝑖 = √21.56 ≈ 4.64 m/s.
Question 6
A pipe 2.5 m above a creek discharges water horizontally at 1.5 m/s. How far horizontally from
the end of the pipe does the water hit the creek?
A) 0.71 m
B) 1.07 m
C) 2.50 m
D) 1.50 m
E) 0.55 m
Correct Answer: B) 1.07 m
Rationale: First, find the time to fall:
𝑡 = √2ℎ/𝑔 = √5.0/9.8 ≈ 0.714 s
. Then, find the horizontal distance:
𝑥 = 𝑣𝑥 × 𝑡 = 1.5 m/s × 0.714 s ≈ 1.07 m

B) 1.56 m/s²
C) 6.25 m/s²
D) 12.50 m/s²
E) 0.63 m/s²
Correct Answer: C) 6.25 m/s²
Rationale: Centripetal acceleration 𝑎 = 𝑣 2 /𝑟
. The diameter is 8.0 m, so the radius 𝑟 = 4.0 m
. 𝑎 = 52 /4 = 25/4 = 6.25 m/s2
.

Correct Answer: C) The padded back of the seat supports the head and back, spreading the
force over time and preventing whiplash.
Rationale: In a head-on collision, the car stops abruptly, but the child continues forward. A
rear-facing seat uses its entire structure to support the child's heavy head and fragile neck,
distributing the impact force over a larger area and a longer time interval.

the net force acting on the car?
A) 1500 N
B) 750 N
C) 3000 N
D) 500 N
E) 100 N
