1. Within 5.0 s of lift-off, a space shuttle reaches an altitude of 525 m, uniformly accelerating during the entire time. 

(a) What is its acceleration?

(b) At what speed is the shuttle travelling when it reaches this altitude?

(c) How long would it take the shuttle to travel the next 525 m if it stops accelerating after 5.0 s?

2.

A ball is thrown vertically upward from a window that is 5.25 m above the ground. The ball's initial speed is 2.8 m/s and the acceleration due to gravity is 9.8 m/s2.

(a) How high does the ball rise?

(b) How fast is it moving when it hits the ground?
