Question:
The brakes are applied to a moving vehicle, causing it to uniformly slow down. While slowing, it moves a distance of m in s to a final velocity of ms at which point the brakes are released.
a What was its initial speed in ms just before the brakes were applied?
How is average velocity related to displacement and time? How is average velocity related to initial and final velocity when acceleration is uniform Use these relationships to solve for initial velocity.
b What was its acceleration in ms while the brakes were applied? Assume the initial direction of motion is the positive direction. Indicate the direction with the sign of your answer.
