12-36.

A ball is thrown from a window

Assume the acceleration due to gravity is

m/sec ^{2}. Write equations forand.Determine the angle at which the ball hits the ground.

First, determine when the ball hits the ground. This is when

.Then angle is the angle created by the slope.

Think of drawing a slope triangle and calculating the angle.
