A glass ball collides with a smooth horizontal surface (`xz` plane) with a velocity `V = ai- bj`. If the coefficient of restitution of collision be `e`, the velocity of the ball just after the collision will be

A glass ball collides with an identical ball at rest with v_(0)=2 m/sec. If the coefficient of restitution of collision is e = 0.5, find the velocities of the glass balls just after the collision.

A glass ball collides with an identical ball at rest with v_(0)=2 m/sec. If the coefficient of restitution of collision is e = 0.5, find the velocities of the glass balls just after the collision.

A ball of mass m is projected with a velocity 'u' at angle theta with the horizontal. It collides with a smooth box of mass 'M' at its highest position. If the co-efficient of restitution is 'e' . FInd the velocity of the ball after collision

A ball A moving with a certain velocity collides, with another ball B of the same mass at rest. If the coefficient of restitution is e, the ratio of the velocities of A and B just after the collision is

A ball moving with speed v collides with a horizontal smooth surface at an angle theta with normal to surface as shown in figure. If coefficient of restitution of collision is e, then find v'

A ball moving with speed v collides with a horizontal smooth surface at an angle theta with normal to surface as shown in figure. If coefficient of restitution of collision is e, then find v'

A ball P is moving with a certain velocity v , collides head-on with another ball Q of same mass at rest. The coefficient of restitution is 1/4, then ratio of velocity of P and Q just after the collision is
