ln The figure, a block of ice slides down a frictionless ramp at angle e 60° while an ice worker pulls on the block (via a rope) with a force Fr has a magnitude of 60 N and is directed up the ramp. As that kinetic the block slides through distance 0 m along the ramp, its the energy increases by 90 J. How much greater would its kinetic energy have been if rope had not been attached to the block?
