Physics - W.E.P. Question with Solution | TestHub

A block $A$ of mass $m$ is moving on a frictionless horizontal plane towards a smooth wedge (B) of mass $2m$, which is kept at rest on smooth horizontal plane at $\mathrm{t}=0$, At $\mathrm{t}={\mathrm{t}}_1$, it is found that both block & wedge is moving with same velocity and at $\mathrm{t}={\mathrm{t}}_2$ it is found that block & wedge are again moving on the horizontal frictionless plane. In list-I work done by different forces are given and in list-II value of work done by those forces are given.
