k wind m The figure above shows one end of a spring of force constant k that is attached to a wall, and the other end is attached to a block of inertia m sitting on a horizontal surface. You pull on the block and stretch the spring by a distance d past its relaxed position, then hold the block at that position. A steady wind exerts a constant force directed to the left. When you release the block, it moves to the left, experiencing a frictional force, of magnitude F, until equilibrium is reached with the spring compressed a distance 2d from its relaxed position. Draw an energy diagram for this process by choosing the system as the block, spring and surface and explain your results.
