Question

Two friends Virat and Veeru are on roller skates standing near by and facing each other. The masses of Virat and Veeru are 40 kg and 48 kg respectively. Virat throw a ball of 2 kg with a speed of 10 ms–1 horizontally toward Veeru and Veeru catches it. What is distance between them 2 second after Virat throws the ball?

Answer 1

Answer:

The separation between them will increase. Initially, the momentum of both of them is zero as they are at rest. In order to conserve the momentum the one who throws the ball would move backward. The second will experience a net force after catching the ball and therefore will move backward that is in the direction of the force.
