A ball is thrown toward the ground. The figure shows the direction of the ball before it reaches the ground and the direction of the ball after it bounces off the ground. After the bounce, the ball leaves the ground with the same speed that it had before the bounce. The angle between the ground and the ballâs direction of travel is θ0 before and after the ball bounces off the ground. The positive directions are indicated in the figure.
