Question: In Figure, a bar of mass m falls freely (neglecting air drag). A hook is attached to the left end of the bar. When the hook collides with a pin on its path at the velocity vj , the bar will begin to rotate around the pin. The physical parameters are m = 1 kg, L = 1 m, vj = 1 m/s
Tasks: (a) Find the velocity of the center of the bar immediately following the collision.
(b) Calculate the fractional change in kinetic energy before and after the collision.
(c) Determine the EOM after the collision.
