1) A roller coaster's velocity at the top of a hill is 10 m/s. Four seconds later
it reaches the bottom of the hill with a velocity of 36.2 m/s. What is the
acceleration of the coaster?
2) A car traveling at 31.5 m/s starts to decelerate steadily. It comes to a stop
in 9 seconds. How far did the car travel during these 9 seconds? (Hint: you
need to know the acceleration)
3) A train is traveling at a certain speed. When the conductor applies the
brakes, it takes 1 minute and 25 seconds to stop. If the acceleration rate is
(-)0.8m/s?, what was the initial velocity of the train?
