Question:

A rubber ball is dropped onto a ramp that is tilted at 20°, as shown in FIGURE P4.59. A bouncing ball obeys the €œlaw of reflection,€ which says that the ball leaves the surface at the same angle it approached the surface. The ball€™s next bounce is 3.0 m to the right of its first bounce. What is the ball€™s rebound speed on its first bounce?
