A ball rolls along a desktop with an uniform velocity of 3 m/s. What is the displacement after 10 seconds have passed?
A ball is thrown upward with an initial velocity of 18 m/s? What is the maximum height the ball reaches if the ball is assumed to leave from the ground?
A ball is dropped from a 35 m tall building. The ball takes how long to impact the ground?

(a) A ball rolls along a desktop with an uniform velocity of 3 m/s. What is the displacement after 10 seconds have passed?
D = V*t
(b) A ball is thrown upward with an initial velocity of 18 m/s?
Vo^2/2 = g H
Solve for height, H
(c) A ball is dropped from a 35 m tall building. The ball takes how long to impact the ground
35 = (g/2) t^2
Solve for time, t.
