A 127.0 N carton is pulled up a frictionless baggage ramp inclined at 27.0 ∘ above the horizontal by a rope exerting a 75.2 N pull parallel to the ramp's surface. The carton travels 6.05 m along the surface of the ramp.

b) Calculate the work done on the carton by the gravity.

c) Calculate the work done on the carton by the normal force of the ramp.

d) What is the net work done on the carton?

e) Suppose that the rope is angled at 49.0 ∘ 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?

Block 1 (10 kg) is pulled by a rope from left to right up a ramp which is inclined 45 degrees from the horizontal. The rope pulls on block 1 with a force of 150 N parallel to the surface of the inclined plane. The coefficient of kinetic friction between the block and the surface equals 0.4. On a sheet of paper, draw the free body diagram for block 1 using the two-subscript notation from class. Assume that the x-axis...

A mass m = 13 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk = 0.07, for a distance d = 5.1 m. Then the mass is continued to be pulled up a frictionless incline that makes an angle θ = 33° with the horizontal. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 33° (thus on the incline it is...
