A ball of mass `1kg` moving with `4m^-1` along +x-axis collides elastically with an another ball of mass `2kg` moving with `6m//s` is opposite direction. Find their velocities after collision.

A ball of mass m moving with velocity v collides elastically with another ball of identical mass coming from the opposite direction with velocity 2v. Their velocities after collisions are-

A ball of mass m moving with a velocity collides head on elastically with another of the same mass m but moving with a - in the opposite direction). After the collision

A ball of mass 4 kg moving with a velocity of 12 m//s impinges directly on another ball of mass 8 kg moving with velocity of 4 m//s in the same direction. Find their velocities after impact and calculate the loss of KE due to impact if e =0.5 .

A ball of mass 4 kg moving with a velocity of 12 m//s impinges directly on another ball of mass 8 kg moving with velocity of 4 m//s in the same direction. Find their velocities after impact and calculate the loss of KE due to impact if e =0.5 .

A ball of mass M moving with a velocity v collides perfectly inelastically with another ball of same mass but moving with a velocity v in the opposite direction. After collision

A body of mass 0.5 kg moving with a velocity of 6 m//s collides with another body of mass 2 kg moving at 2 m//s and travelling in opposite direction. If the two bodies travel together after the collision, find the velocity of combined mass and the loss of kinetic energy.
