Solution

The correct option is A $V_{0}$
According to work-energy equation the particle goes back to the same height so there will be no change in kinetic energy. Thus the velocity will be same as the initial velocity.

Two bodies A and B of mases m and 2m respectively are placed on a smooth floor. They are connected by a spring. A third body C of mass m moves with velocity $v_{0}$ along the line joining A and B and collides elastically with A as shown in figure. At a certain instant of time $t_{0}$ after collision, it is found that the instantaneous velocities of A and B are the same. Further at this instant the compression of the spring is found to be $x_{0}$ . Determine (a) the common velocity of A and B at time $t_{0}$ and (b) the spring constant.
