A ball is tossed so that it bounces off the ground, rises to a height of 0.90 m, and then hits the ground again 0.50 m away from the first bounce.
How long is the ball in the air between the two bounces?
What is the ball's velocity in the x-direction?
What is the ball's speed just before the second bounce?
What is the angle of the velocity vector with respect to the ground right after the first bounce?
