A block of mass m moving with a certain speed collides with another identical block at rest . If coefficient of restitution is 1/(sqrt(2)) then find ratio of intial kinetic energy to kinetic energy lost in 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.
