In the figure here, a block of ice slides down a frictionless ramp at angle 0=50.0 ° while an ice worker pulls on the block (via a rope) with a force that has a
magnitude of 52.0 N and is directed up the ramp. As the block slides down through distance d = 0.560 m along the ramp, its kinetic energy increases by 82.0
J. How much greater would its kinetic energy have been if the rope had not been attached to the block?
