A hollow sphere with r = 8.1 cm and mass 0.25kg rolls down a ramp with an angle 15 degree above the horizontal that is 1.5m high. What is the velocity of the sphere when it reaches the end?
How much of total kinetic energy is rotational?
Pls Help!!

For a hollow sphere, I = k*m*r² where k = (2/3)
Vb = √[2gh/(1+k)] = 4.2 m/s
KEr/KEtot = k/(1+k) = 0.40
Vb = √[2gh/(1+k)] = 4.2 m/s
KEr/KEtot = k/(1+k) = 0.40
