Two blocks A and B. each of mass m, are ...

Two blocks `A` and `B`. each of mass `m`, are connected by a massless spring of natural length `I`. and spring constant `K`. The blocks are initially resting in a smooth horizontal floor with the spring at its natural length, as shown in Fig. A third identical block `C`, also of mass `m`, moves on the floor with a speed `v` along the line joining `A` and `B`. and collides elastically with `A`. Then

A

The kinetic energy of the A-B system, at maximum compression of the spring is zero

B

The kinetic energy of the A-B system, at maximum compression of the spring is `mv^(2)//4`.

C

The maximum compression of the spring is `vsqrt((m//2K))`
