A simple pendulum , made of a string of length l and a bob of mass m, is released from a small angle `theta_(0)` it strikes a block of mass M, kept on a horizontal surface at its lowest point of oscil,ations , elastically , it bounces back and goes up to an angle `theta)(1-)` then M is given by :

A simple pendulum of length l and consisting of a ball of mass m is released from a position making an angle theta=cos^(-1) (0.8) with the vertical and strikes at its lowest position a block of mass M resting on a rough horizontal plane. If the coefficient of kinetic friction between the plane and the block is 0.2 find (a) How long the block will move along the plane, if the ball of the pendulum rebounds to an angle beta=cos^(-1) (0.9)A (b) The coefficient of restitution, use (M)/(m) =10 and 1= 1 m

A simple pendulam of length .l. carries a bob of mass .m.. The bob is released from horizontal position. The tension in the string at t he lowest point would be

The ball A of mass m is released when the string is horizontal. It strikes a block B of mass 3 m kept on a rough surface of friction coefficient mu = 0.1 . If a head on elastic collision takes place , find the maximum distance travelled by the block on a rough surface.
