In the picture above the sphere is solid and has a mass of 4kg and a radius of 0.01m. The ramp has a length of 6m and is angled 30 degree from the floor. The moment of inertia for a solid sphere is 2 over 5 m r squared. If the sphere starts from rest and there is enough friction to keep it from slipping, then what is the linear speed at the bottom of the incline?
