A 124.0 N carton is pulled up a frictionless baggage ramp inclined at 25.0 ∘ above the horizontal by a rope exerting a 74.6 N pull parallel to the ramp's surface. The carton travels 5.20 m along the surface of the ramp. Suppose that the rope is angled at 47.2 ∘ above the horizontal, instead of being parallel to the ramp's surface. How much work does the rope do on the carton in this case?

Question
A 124.0 N carton is pulled up a frictionless baggage ramp inclined at 25.0 ∘ above the horizontal by a rope exerting a 74.6 N pull parallel to the ramp's surface. The carton travels 5.20 m along the surface of the ramp.
Suppose that the rope is angled at 47.2 ∘ above the horizontal, instead of being parallel to the ramp's surface. How much work does the rope do on the carton in this case?
