To make a bounce pass, a player throws a 0.60-kg basketball toward the floor. The ball hits the floor with a speed of 5.5 m/s at an angle of 59° from the vertical. If the ball rebounds with the same speed and angle, what was the impulse delivered to it by the floor?

The impulse delivered by the floor equals the momentum change in the vertical direction.

That is equal to 2*M*Vcos55

The horizontal velocity component does not change during the bounce.

In this case, I=2MVsin31
