EXAMINATION TEST 2026 QUESTIONS
WITH COMPLETE SOLUTIONS GRADED A+
⩥ Examine the position vs. time graph below. What is the velocity of the
object at t = 5.0 s? Answer: -5 m/s
⩥ A student measures the mass of an object at 4.68 g and the volume of
the object at 2.3 mL. The student calculates the density as 2.03478
g/mL. A second student disagrees with the density. Which of the
following statements would explain why the second student disagrees?
Answer: The number of decimals in the answer does not show proper
precision.
⩥ Examine the position vs. time graph below. Which of the following
correctly describes the motion of the object? Answer: Forwards at a
constant speed and then backward at a constant speed
⩥ A car moving at a constant 25 m/s travels for 3.0 seconds. What is the
distance traveled by the car? Answer: 75 m
⩥ A student measures the mass of an object at 4.68 g. Which of the
following statements is most accurate? Answer: he first two digits are
measured and the last digit is estimated.
, ⩥ A student models the constant speed motion of an object with the
following equation:
x = (4 m/s) t + (-15 m)
Which of the following descriptions of motion is consistent with this
equation? Answer: The object starts at a negative position and travels
forwards.
