A pendulum bob of mass m at the end of a string l starts from rest with the string taut and horizontal. When it reaches its vertical position, it strikes an object of mass 2m which is resting on a frictionless horizontal surface. The collision is perfectly elastic. Calculate: O The velocity of the bob just before the impact ® The velocity imparted to the stationary object by the impact
