A block A is placed over a long rough plank B same mass as shown below. 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 velocity of A & B at time 't'. Then choose the correct graph between `v_(1)` or `v_(2)` and t.
