A spherical shell (m = 10kg and r=sqrt(3)) is rolling (without slipping) along a horizontal surface, moving toward an incline. The shell's rotational speed at the bottom of the ramp is 2 rad/s.

a.) What is the total energy of the ball at the bottom of the ramp?

b.) What height will the shell reach on the ramp before stopping?

c.) What heigght would it have reached if the ramp was frictionless?

d.) Would the shell go higher if it was a solid disk or a hoop?

A hollow sphere (mass 8.8 kg, radius 54.8 cm) is rolling without slipping along a horizontal surface, so its center of mass is moving at speed vo. It now comes to an incline that makes an angle 56o with the horizontal, and it rolls without slipping up the incline until it comes to a complete stop. Find a, the magnitude of the linear acceleration of the ball as it travels up the incline, in m/s2.
