Two balls of masses m_(1), m_(2) and speeds v_(1) and v_(2) collide at right angle . The maximum amount of kinetic energy loss due ot inelastic collision is ___.

In an arrangement shown , bob A on the left is pulled aside . It is then released and allowed to collide with other bob B which is at rest . A perfectly inelastic collision occurs and the system rises to a height h/4 . The ratio of the masses of the bobs is

Statement -1: Two particles moving in the same direction do not lose all their energy in a completely inelastic collision. Statement -2 : Principle of conservation of momentum holds true for all kinds of collisions.
