The brakes are applied to a moving van, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 8.20 s to a final
velocity of 1.90 m/s, at which point the brakes are released.
(a) What was its initial speed (in m/s), just before the brakes were applied?
m/s
(b) What was its acceleration (in m/s2) while the brakes were applied? (Assume the initial direction of motion is the positive direction. Indicate
the direction with the sign of your answer.)
m/s²
