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 1 kg ball moving at 12 m//s collides head on with a 2g ball moving in the opposite direction at 24 m//s . The velocity of each ball after the impact, if the coefficient of restitution is 2//3 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 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 ball P moving with a speed of v ms collides directly with another identical ball Q moving with a speed 10ms' in the opposite direction. P comes to rest after the collision. If the coefficient of restitution is 0.6 the value of v is

A ball of mass m moving with velocity u strikes another identical ball at rest. Find the velocities of the balls after the collision if the coefficient of restitution is e and the collision is head -on. Also , calculate the loss in K.E.

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 2m impinges directly on a ball of mass m, which is at rest. If the velocity with which the larger ball impringes be equal to the velocity of the smaller mass after impact then the coefficient of restitution :-
