**drwls**, Tuesday, November 8, 2011 at 8:07pm(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.
