A smooth ball of mass m is suspended from a light string of length 1 m. Another ball of mass 2 m strikes the ball of mass in horizontally with a speed of u = root 35 m/s. The coefficient of restitution for the collision is e. The string becomes loose, when it makes an angle of 30∘ with the horizontal, find the value of e.

Two identical balls A and B lie on a smooth horizontal surface, which gradually merges into a curve to a height 3.2m. Ball A is given a velocity of 10m/s, to collide head-on with ball B, which then takes up the curved path. What is the minimum coefficient of restitution, e, for the collision between A and B in order that ball B reaches the highest point C of the curve.

Three balls of masses m1,m2 and m3 are lying in a straight line. The first ball is moved with a certain velocity so that it strikes the second ball directly and itself comes to rest. The second ball collides with the third and is itself reduced to rest. If e is the coefficient of restitution for each ball, write down the relation of m3 in terms of m1 and m2.
