A ball A of mass 3 m is placed at a distance d from the wall on a smooth horizontal surface Another ball B of mass m moving with velocity u collides with ball A . The coefficient of restitution between the balls and the wall and between the balls is e (a) the velocity of ball B after collision is (u(3e-1))/(4) . (b) the velocity of ball B after collision is (u(2e-1))/(4) . ( c) after collision, ball A will have away by distance (d(2e-1))/((2e-1)) during the time ball B returns back to wall. (d) after collision, ball A will move away by distance (d(e-1))/((3e-1)) during the time ball B returns back to wall.

A ball of mass m moving with a speed 2v_0 collides head-on with an identical ball at rest. If e is the coefficient of restitution, then what will be the ratio of velocity of two balls after collision?

A ball of mass m moving with a speed 2v_0 collides head-on with an identical ball at rest. If e is the coefficient of restitution, then what will be the ratio of velocity of two balls after collision?

A small ball of mass m collides with as rough wal having coeficient of friction mu at an angle theta with the normal to the wall. If after collision the ball moves wilth angle alpha with the normal to the wall and the coefficient of restitution is e , then find the reflected velocity v of the ball just after collision.
