A slender rod of length l and mass m is released from rest, Ask an Expert

Academics

A slender rod of length L and mass m is released from rest in the position shown. It is observed that after the rod strikes the vertical surface it rebounds to form an angle of 30° with the vertical.

(a) Determine the coefficient of restitution between knob K and the surface.

(b) Show that the same rebound can be expected for any position of knob K.
