2kg ball moving at 6ms^(-1) collides head on with a 3kg ball moving in the opposite direction at 12m/s .The velocity of each ball after the impact, if the coefficient of restitution is 1/2, is ?

A 2 kg ball , moving at 10 m//s , collides head - on with a 3 kg ball moving in the opposite direction at 20 m//s . If the coefficient of restitution is 1//3 , then the energy lost in the collision is

A 1kg ball,moving at 12ms^(-1) collides head-on with a 2kg ball moving in the opposite direction at 24ms^(-1) .If the coefficient of restitution is (2)/(3) , then the energy lost in the collision is:

A 1 kg ball moving with a speed of 6" ms"^(-1) collides head - on with a 0.5 kg ball moving in the opposite direction with a speed of 9" ms"^(-1) . If the coefficient of restitution is (1)/(3) , the energy lost in the collision is

A ball collides with an inclined plane of inclination theta after falling through a distance h. if it moves horizontal just after the impact, the coefficient of restitution is

A ball of mass 2kg moving with speed 5m/s collides directly with another ball of mass 3kg moving in the same direction with speed 4m/s. The coefficient os restitution is 2/3. Find the velocities of both ball after the collision.
