1.	A simple pendulum is made of a string of length l and a bob of mass m, is released from a small angle θ0. It strikes a block of mass M, kept on a horizontal surface at its lowest point of oscillations, elastically. It bounces back and goes up to an angle θ1. Then, M is given by
Answer» A simple pendulum is made of a string of length $l$ and a bob of mass $m$ , is released from a small angle $θ_{0}$ . It strikes a block of mass $M$ , kept on a horizontal surface at its lowest point of oscillations, elastically. It bounces back and goes up to an angle $θ_{1}$ . Then, $M$ is given by
