A hollow sphere (M = 7.69 kg, R = 0.648 m) is rolling without slipping on a horizontal surface with its center of mass moving at linear speed vo when it comes to a rising incline that makes an angle of = 33.7o with the horizontal. The ball now rolls without slipping up the incline.
a) Find a, the magnitude of the linear acceleration of the ball on the incline.
b) Find f, the magnitude of the force of static friction exerted by the incline on the ball.
c) If the ball rolls distance d = 2.8 m up along the incline before coming to rest: find vo, the initial linear speed of the ball.
