Problem 5: Arod of mass M= 2.6 kg and length L can rotate about a hinge at its left end
and is initially at rest. A putty ball of mass m = 55 g, moving with speed v = 5.41 m/s, strikes the rod
at angle e = 63° from the normal at a distance D = 2/3 L, where L = 1.25 m, from the point of
rotation and sticks to the rod after the collision.
