138.The blocks shown in figure have equal masses. The surface of A is smooth but that of B has a friction coefficient of 0.1 with the floor. Block A is moving at a speed of 10m/s towards B which is kept at rest. Find the distance travelled by B if(a)the collision is perfectly elastic and(b) the collision is perfectly inelastic
