A clay ball of mass m and speed v strikes another metal ball. of same mass m, which is at rest. They stick together after collision. The kinetic energy of the system after collision is –

A billiard ball of mass M , moving with velocity v_1 collides with another ball of the same mass but at rest . If the collision is elastic , the angle of divergence after the collision 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 body of mass 4 kg moving with velocity 12 m//s collides with another body of mass 6 kg at rest. If two bodies stick together after collision , then the loss of kinetic energy of system is

A body of mass 4 kg moving with velocity 12 m//s collides with another body of mass 6 kg at rest. If two bodies stick together after collision , then the loss of kinetic energy of system is

A body of mass 4 kg moving with velocity 12 m//s collides with another body of mass 6 kg at rest. If two bodies stick together after collision , then the loss of kinetic energy of system is

A ball moving with speed v hits another identical ball at rest. The two balls stick together after collision. If specific heat of the material of the balls is S , the temperature rise resulting from the collision is
