1. The problem statement, all variables and given/known data To basketball player bounces the 0.60-kg basketball to another player by bouncing it off the court. The ball hits the court with a speed of 6.5 m/s at an angle of 50° from the vertical. If the ball rebounds with the same speed and angle, what was the impulse delivered to it by the court? 2. Relevant equations I know that Impulse is the change in momentum, or the force times the change in time. 3. The attempt at a solution I cannot figure out how to find the Impulse with simply the velocity an angles. Is there a change in momentum if all it does is change direction? If so, how do I use the angles to calculate the change? I try doing the x/y components of the velocity but it seems to cancel out.
