Homework Help: Physics

Posted by Tom Atlus on Saturday, January 8, 2011 at 2:53pm.

A golf ball strikes a hard, smooth floor at an angle of θ = 29.6 and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.041 kg, and its speed is 45 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.)
