A golf ball strikes a hard, smooth floor at an angle of 25.8 ° and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.0147 kg, and its speed is 36.8 m/s just before and after striking the floor. What is the magnitude of the impulse applied to the golf ball by the floor? (Hint: Note that only the vertical component of the ball's momentum changes during impact with the floor, and ignore the weight of the ball.)
