The adjacent figure shows an infinite fram of two sides in a gravity - free space. What is the final constant kinetic energy expected of the ball of mass m projected as shown with an initila velocity `v_0`? The coefficient of restitution for the collision between the ball and the frame is `e = 0.5`.

Two identical balls A and B are moving as shown in the fig. Ball A hits a smooth floor head on with a velocity u and at the same instant ball B strikes A head on with a horizontal velocity u. The collision between A and B is perfectly inelastic whereas the coefficient of restitution for collision between A and the floor is e = 0.5 . At what time the two balls will collide again? Assume friction to be absent everywhere.

A ball of mass m moving at speed v makes a head on collision with an identical ball at rest. The kinetic energy of the balls after the collision is 3//4th of the original. Find the coefficient of restitution.

Rod can rotate about hinge point 'P'. A ball of mass 'm' is projected with a velocity 5v_(0) in a gravity free space as shown in figure. Collision between the rod and the ball is perfectly elastic. Then find the magnitude of velocity of ball after the collision ( neglect the friction between the ball and the rod during the collision ).

A ball of mass m moving at a speed v makes a head-on collision with an identical ball at rest. The kinetic energy of the balls after the collision is three fourths of the original. Find the coefficient of restitution.
