Homework Statement

A ball is thrown from a height of 12.0 m above the ground level. If it takes 1.25 s to reach the ground:

a) Calculate its starting velocity
b) If the ball lands 40.0 m horizontally out from the throwing point, what horizontal velocity did it have?
c) Determine the speed and direction of the launch velocity
