Angular Momentum

Angular momentum

A .015 kg coin of diameter .013 m is spinning at 9 rev/s about a vertical diameter at a fixed point on a tabletop. a) If the coin spins about a vertical diameter at 9 rev/s while its center of mass travels in a straight line across the tabletop at .05 m/s, what is the angular momentum of the coin about a point on the line of mot

Mechanics problem

If a rigid homogeneous rectangular crate of mass m and height h slides on its base of w, while traveling a velocity v, it stikes a low, immovable curb. What is the angular velocity of the crate immediately after the impact, in terms of m,w,h,v; and under what condition (in m,w,h,v) will the crate fall over on its side?
