Two identical blocks A and B, each of mass 'm resting on smooth floor are connected by a light spring of natural length I and the spring constant k, with spring at its natural length. A third identical block C (mass$$ $$m) moving with a speed v along the line joining A and B collides with A. The maximum compression in the spring is

Question

Infinity Learn · Accepted Answer

The kinetic energy of moving mass is equal to the total potential energy of the combined masses due to compression x,$$12mv2=12kx2+12kx2=kx2$$ or $$x=Vm2k$$
