In the figure, a crate of mass m = 109 kg is pushed at a constant speed up a frictionless ramp (0 = 29°) by a horizontal force F. The positive direction of an x axis is up the ramp, and the positive direction of a y axis is perpendicular to the ramp. (a) What is the magnitude of F? (b) What is the magnitude of the normal force on the crate?
