A frictionless roller coaster cart is moving at 8.9 m/s when it is 31.7 m above the ground. It coasts along the hilly track, at one point reaching the top of hill, 11.1 m above the ground. Find the cart's speed at the top of the hill. V= m/s Record your numerical answer below, assuming three significant figures. Remember to include a "_"1 if/when necessary.

A roller coaster car has a speed of V0= 8.1 m/s as it tops the crest of a h= 25 m drop. What is the cars speed at the bottom of the drop? Vf in m/s?
A hare and a tortoise compete in a race over a straight course 1.00 km long. The tortoise crawls at a speed of 0.200 m/s toward the finish line. The hare runs at a speed of 8.00 m/s toward the Finish line for 0.800 km and then stops to tease the slow-moving tortoise as the tortoise eventually passes by. The hare waits for a while after the tortoise passes and then runs toward the finish line again at 8.00 m/s. Both the hare and the tortoise cross the finish line at the exact same instant. Assume both animals, when moving, move steadily at their respective speeds. (a) How far is the tortoise from the finish line when the hare resumes the racer (b) For how long in time was the hare stationary?
