In the figure here, a block of ice slides down a frictionless ramp at angle 9-51.0" while an ice worker pulls on the block (via a rope) with a force that has a magnitude of 56.0 N and is directed up the ramp. As the block slides down through distance d-0.450 m along the ramp, its kinetic energy increases by 80.0 J. How much greater would its kinetic energy have been if the rope had not been attached to the block?
