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 7.70 s to a final velocity of 1.80 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/s^2) 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/s^2
