Question

In the figure here, a block of ice slides down a
frictionless ramp at angle 0-51.0° while an ice
worker pulls on the block (via a rope) with a force
that has a magnitude of 59.0 N and is directed up the
ramp. As the block slides down through distance d
0.410 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?
