Question

A sphere of mass 10kg moving with velocity 20ms-1 collides elastically with a stationary sphere of mass 1miligram.velocity of the lighter.velocity of the lighter sphere just after collision is nearly​

Answer 1

Answer:

Explanation:

Conservation of momentum

m1v1+m2v2=(m1+m2)V

Here m2V2 term will be zero as the second body is in stationary (V2=0)

So,V=m1/(m1+m2)× v1
