Solution

## The correct option is B 20 ms−1In the elastic collision between a heavy object and a very light object at rest, the velocity of particles after collision is for heavy particle, v1=u1for light particle, v2=2u1−u2since, u2=0 hence, v2=2u1Therefore, the stone will fly away with a velocity equal to v2=2u1=2(10)=20ms−1
