A solid 5.3 kg sphere of diameter 13 cm rolls up a ramp that is at 30° relative to the horizontal. At the bottom of the ramp the center of mass of the sphere has a translational speed of 1.2 m/s. a. What is the kinetic energy of the sphere at the bottom of the ramp? b. How far up the ramp does the sphere go? c. If the mass of the sphere doubles and the radius is tripled, how does the answer to part b change? Explain.
