Two identical simple pendulums A and B are fixed at same point. They are displaced by very small angles alpha and beta ( beta gt alpha) and released from rest. Find the time after which B reaches its initial position for the first time. Collisions are elastic and length of strings is l .

A small ball is suspended from a fixed point 'O' by means of a light and inextensible string of length 'l'. The ball is first taken aside such that string becomes horizontal and then released from rest. At the borrom it collides with a fixed obstacle. The co-efficient of restitution is 'e'. Find the maximum angular deflection of the string after n^(th) collision.

A light rigid rod has a small ball of mass m attached to its one end. The other end is hinged on a table and the rod can rotate freely in vertical plane. The rod is released from vertical position and while falling the ball at its end strikes a hemisphere of mass m lying freely on the table. The collision between the ball and the hemisphere is elastic. The radius of hemisphere and length of the rod are R and 2R respectively. Find the velocity of the hemisphere after collision.

A ball of mass 0.01 kg is suspended from a fixed point O by means of a light and inextensible string of length 10m. The ball is first taken aside such that string becomes horizontal and then released from reast. At the lowermost point of its path, it hits a stationary small block of mass 1.205kg lying on a rough horizontal surface. After striking the block, the ball rebounds and comes to rest when the string makes an angle of 30^@) with the horizontal . Due to the impact the block moves through a distance of 0.5m on the horizontal surface. Find the coefficient of friction between the block and the surface.
