Two bodies `P` and `Q` of masses `m_(1)` and `m_(2)` `(m_(2) gt m_(1))` are moving with velocity `v_(1)` and `v_(2)` force exerted by `P` on `Q` during the collision is

Two bodies A and B of masses m, and m, moving with velocities V_(1) and V_(2) respectively collide. If m_(2) gt m_(1) then the force exerted by B on A during the collision is

Two bodies of masses m_(1) and m_(2) are moving with velocity v_(1) and v_(2) respectively in the same direction. The total momentum of the system in the frame of reference attached to the centre of mass I (v is relative velocity between the masses)
