Answer» Two blocks of equal masses are placed on a horizontal surface. The surface of $A$ is smooth but that of $B$ has a friction coefficient of $0.2$ with the floor. Block $A$ is given a speed $5 m/s$ , towards $B$ which is kept at rest. Find the distance travelled by $B$ , if the collision is perfectly elastic. (take $g = 10 {m/s}^{2}$ )
