The blocks shown in figure (9-E19) have equal masses.
The surface of A is smooth but that of B has a friction
coefficient of 0.
10 with the floor. Block A is moving at
a speed of 10 m/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. Take g
= 10 m/s 2
