Question

ame that an object is moving with constant acceleration. Which of the following is an accurate statement boncerning its motion? (a) In equal times it's speed increases by equal amounts. (b) In equal times it's velocity changes by equal amounts (c) In equal times it moves equal distances (d) None of the above is true. 2. A can, after an initial kick, moves up along a smooth incline plane of ice, comes to stop and moves down. It will (a) travel at constant velocity (b) have a constant acceleration up the hill, but a different constant acceleration when it comes back down the hill (c) have the same acceleration, both up the hill and down the hill d) have a varying acceleration along the hill. 3. Objects A and B both start from rest. They both accelerate at the same rate. However, object A accelerates for twice the time as object B. What is the distance traveled by object A compared to that of object B? (a) the same distance (b) twice as far (c) three times as far (d) four times as far 4. A ball is thrown vertically upward with a speed v. An identical second ball is thrown upward with a speed 2v. How many times higher does the second ball go than the first one? (a) 4 (b) 2 S. Ball A i dropped from the top of a building. One second laster, ball B is dropped from the same building. As time progresses, the difference in their speeds (a) increases (b) remains constant (c) decreases (d) cannot be determined from the information given

Explanation / Answer

Correct answer: Option (b): In equal times its velocity changes by equal amount.

Reference formula: Acceleration, a = (v - u)/ t

As time changes with motion, to maintain the constant value of acceleration, velocity will change by equal amount.
