A specially constructed sphere with a mass of M = 3.9 kg k g , and a radius of R = 40 cm c m starts from rest at the top of a ramp and rolls down without slipping. The top of the ramp is h = 8.7 m m above its foot. Choose the foot of the ramp to be the reference point for gravitational potential energy. The moment of inertia of this specially constructed sphere is given by 23MR2 2 3 M R 2 (NOT the usual 25MR2 2 5 M R 2 for a common solid sphere).Find the angular speed of the sphere at the foot of the ramp
