A solid sphere of radius 37 cm is positioned at the top of an incline that makes 22 ◦ angle with the horizontal. This initial position of the sphere is a vertical distance 3.1 m above its position when at the bottom of the incline. The sphere is released and moves down the incline. 37 cm M µ ℓ 22 ◦ 3.1 m Find the speed of the sphere when it reaches the bottom of the incline if it rolls without slipping. The acceleration of gravity is 9.8 m/s 2 and the moment of inertia of a sphere with respect to an axis through its center is 2 5 M R2 . Answer in units of m/s
