On the Tower of Terror ride at Walt Disney World riders are taken to the top of a 200 foot tower and then dropped into free fall for several seconds until the brakes are applied and the car comes to a smooth stop. Recall the height of object under the influence of gravity is given by: s(t) = s₀ + v₀t + 1/2 gt².

a. Assuming you are in free fall for 150 feet, what velocity do you reach?

b. Is acceleration positive or negative before the brakes are applied? Explain.

c. Is acceleration positive or negative after the brakes are applied? Explain.

d. With what velocity do you hit the ground if you were allowed to free fall from 200 feel?
