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?

(i) A block of mass m moving towards right with a velocity V strikes (head on) another block of mass M which is at rest connected to a spring. The coefficient of restitution for collision between the blocks is e = 0.5. Find the ratio (M)/(m) for which the subsequent compression in the spring is maximum. There is not friction. Ball A collides head on with another identical ball B at rest. Find the coefficient of restitution if ball B has 80% of the total kinetic energy of the system after 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 moving with a velocity v and it suffers head - on collision with another identical ball at rest . What should be the coefficient of restitution if one - fourth of initial kinetic energy is lost in collision ?

Ball 1 collides directly with another identical ball 2 at rest. Velocity of second ball becomes two times that of 1 after collison. Find the coefficient of restitution between the two balls?

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

A sphere of mass m moving with a uniform velocity v hits another identical sphere at rest. If the coefficient of restitution is e, the ratio of the velocities of the two sphere after the collision is (e-1)/(e+1) .
