Question: A thin rod of mass m = 0.15 kg and length L = 1.2 m is held vertically with one end on the floor and is then allowed to fall.
Part I: What is the total kinetic energy of the rod when it hits the floor, assuming that the end on the floor does not slip?
Part II: What is the linear speed of the end of the rod that hits the floor at the instant when it hits the floor?
