Chapter 10, Problem 93GP

Predict/Calculate A solid sphere with a diameter of 0.17 m is released from rest; it then rolls without slipping down a ramp, dropping through a vertical height of 0.61 m. The ball leaves the bottom of the ramp, which is 1.22 m above the floor, moving horizontally (Figure 10-42). (a) Through what horizontal distance d does the ball move before landing? (b) How many revolutions does the ball make during its fall? (c) If the ramp were to be made frictionless, would the distance d increase, decrease, or stay the same? Explain.
