Q.

A block A is placed over a long rough plank B of same mass as shown in figure. The plank is placed over a smooth horizontal surface. At time t=0, block A is given a velocity $v_{0}$ in horizontal direction. Let $v_{1}$ and $v_{2}$ be the velocities of A and B at time t. Then choose the correct graph between $v_{1}$ or $v_{2}$ and t.

Detailed Solution

Friction between A&B accelerates B and retards A till slipping is stopped. As they have same mass, acc. of B = retardation of A = µg

v_{A} = v_{0} - μ g t, v_{B} = μ g t

Final velocity of A and B = $\frac{m v_{0}}{m + m} = \frac{v_{0}}{2}$
