A golf ball strikes a hard, smooth floor atan angle of θ = 26.4° and, as the drawing shows, rebounds at the sameangle. The mass of the ball is 0.037kg, and its speed is 45 m/s just before and after striking thefloor. What is the magnitude of the impulse applied to the golfball by the floor? (Hint: Note that only the vertical component of the ball's momentum changes during impact with the floor.)_______________N·s
