Two pendulums each of length l are initially situated as shown in Fig. The first pendulum is released and strikes the second. Assume that the collision is completely inelastic and neglect the mass of the string and any frictional effects. How high does the centre of mass rise after the collision?

An object initially at rest explodes into three fragments A B and C. The momentum of A is piˆ and that of B is 3–√p jˆ where p is a + ve number. The momentum of C will be
