A golf ball strikes a hard, smooth floor at an angle of 33.1 ° and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.0510 kg, and its speed is 44.8 m/s just before and after striking the floor. What is the magnitude of the impulse applied to the golf ball by the floor?
A juggler throws a ball straight up with some initial velocity. Half a second later, the juggler throws another ball straight up from the same height, then what is the initial velocity of each ball
