A block A of mass m=5kg is attached with a spring having force constant K=2000N/m. The other end of the spring is fixed to a rough plane A block of mass m is connected rigidly with a smooth wedge (plank) by a light spring of stiffness k. If the wedge is moved with constant velocity v0 find the work done by the external agent till the maximum compression of the spring.
