Question

. A body of mass 1 kg moving with velocity 10 m/s collides with another body moving in opposite
direction of mass 3 kg and velocity 3 m/s. After collision both the bodies move together. What is
their common velocity?
Ans. 0.25 m/s in the direction that of first body​

Answer 1

Answer:

By conservation of linear momentum

1*10 -3*3 = (1 + 3)v

1 = 4v

v = 1/4

v = 0.25m/s

In the direction that of first body
