A ball A of mass 1 kg moving at a speed of 5 ~m / s strikes tangentially another ball B initially at rest. The ball A then moves at right angles to its initial direction at a speed of 4 ~m / s . If the collision is elastic, the mass (in kg ) of ball B and its momentum after collision (in kg - m / s ) respectively are (approximately)
