Two bodies A and B of masses 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 v0 along the line joining A and B and collides elastically with A as shown in fig. At a certain instant of time t0 after comision, it is found that the instantaneous velocities of A and B are the same. Further at this instant the compression of the are the same. Further at this instant the compression of the spring is found to be x0. Determine (i) the common velocity of A and B at time t0 and (ii) the spring constant

collides elastically

Best Answer

Collision between A and C is elastic and mass of both the blocks is same
