A 122.2 N carton is pulled up a frictionless baggage ramp inclined at 27.0 degrees above the horizontal by a rope exerting a 75.6 N pull parallel to the ramp's surface. The carton travels 5.40 m along the surface of the ramp. The work on the carton by the rope is 468 J and 0 J by the normal force.

A. Calculate the work done on the carton by the gravity

B. What is the net work done on the carton?

C. Suppose that the rope is angled at 42.8 degrees 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?
