Re: A problem



Here is a question about which I request list members comments.

A uniform cube with a edge 'a' rests on a horizontal plane whose
friction coefficient equals 'k'. The cube is set in motion with an
initial velocity, travels some distance over the plane and comes to
rest. Explain the disappearance of the angular momentum of the
cube relative to an axis lying in the plane at right angles to the
cube's direction of motion.

regards,

sarma.

the frictional force supplies a torque which changes the angular momentum
