In the figure, a crate of mass m-90 kg is pushed at a constant speed up a frictionless ramp (0-32°) 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? (a) Number (b) Number Units Units
