COMPLETE QUESTIONS CORRECT
ANSWERS
⩥ A ball is attached to the center of the ceiling inside of a van moving at
constant speed. If the ball is released, where will the ball land? Answer:
Directly below its starting position (middle of the van)
⩥ A student fires a bullet horizontally from a gun. Which statement is
most accurate? Answer: The bullet will start to fall as soon as it leaves
the gun.
⩥ The grid below shows the path a student takes through a campus area.
What is the approximate direction of the student's overall displacement?
(Be careful—this is not a position vs. time graph.) Answer: 56°
⩥ A student standing on the edge of a cliff throws a rock downward at a
speed of 7.5 m/s at an angle 40° below the horizontal. It takes the rock
2.4 seconds to hit the ground. How tall is the cliff? Answer: 39.8 m
⩥ A student rolls two balls off of a table. Ball A has twice the mass of
ball B. Both balls leave the table at the same time with the same starting
velocity. Which ball will hit the ground first? (Air resistance is
negligible.) Answer: A will hit the ground at the same time as B.
, ⩥ Vector A has components A = <-2, 5> m/s and vector B has
components B = <6, -2> m/s. What is the magnitude of vector C if C = A
+ B? Answer: 5 m/s
⩥ A student throws a rock horizontally off a 5.0 m tall building. The
rock's initial speed is 6.0 m/s. How long will it take the rock to reach the
ground? Air resistance is negligible. Answer: 1.0 s
⩥ A student fires a bullet horizontally out of a gun. At the same time the
bullet leaves the gun, the student drops a second bullet from the same
height. Which bullet hits the ground first? Answer: The two bullets will
hit the ground at the same time.
⩥ A student rolls two balls off of a table. Ball A has twice the mass of
ball B. Both balls leave the table with the same starting velocity. Which
ball will land further away from the table? (Air resistance is negligible.)
Answer: A and B will land the same distance from the table.
⩥ Mars has a gravitational field strength of 3.7 N/kg near its surface. If
air resistance is negligible, then an object dropped on Mars would have
an acceleration that is Answer: equal to 3.7 m/s2.
⩥ How long will it take an object to travel a distance of 50 m if it starts
from rest and accelerates at a rate of 12 m/s2? Answer: 2.9 s
