Amachine part has the shape of a solid uniform sphere of mass 250 g and a diameter of 4.30 cm. it is spinning about a frictionless axle through its center, but at one point on its equator it is scraping against metal, resulting in a friction force of 0.0200 n at that point.

part (a):

find its angular acceleration. let the direction the sphere is spinning be the positive sense of rotation.

part (b):
how long will it take to decrease its rotational speed by 21.0 rad/s?
