Solution: A box with mass 5.00 kg is placed against a compressed spring. The spring is released and the box slides 4.00 m along a horizontal surface before coming to rest. (At this point the box is no longer in contact with the spring and there is no potential energy left stored in the spring.) The coefficient of kinetic friction between the block and the surface is 0.300. How much energy was initially stored in the compressed spring?
