2) (10pts) Rosanne drops a ball from a height of 400 ft. The force of gravity is 32ft/s/s, which is the acceleration on the ball. So, the velocity is - 32 t (or, you might use 32 t ). a) Find a formula for the height of the ball h ( t ) after t seconds. Be sure to show all your work and reasoning, and check that h (0) = 400. b) How many seconds until the ball hits the ground? (This occurs when h=0, of course).
