A hollow sphere with a mass 1.5 kg and radius 10.9 cm is released from height 4.9 m from the top of an incline. The angle of the inclined plane is p = 30° with respect to the horizontal. What is the speed of the sphere at the base of the incline... (a) in the case that it slides frictionlessly witout rolling. (b) in the case that it rolls without slipping (c) Compare the time intervals required to reach the bottom in cases (a) and (b). (Hint: For this part, you can use Newton's Second Law for linear and rotational motion.)
