a crate of mass m = 98 kg is pushed at a constant speed up a frictionless ramp ( = 27) by a horizontal force

a crate of mass m = 98 kg is pushed at a constant speed up a frictionless ramp (θ = 27°) by a horizontal force Modifying Above Upper F With right-arrow. 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 Modifying Above Upper F With right-arrow? (b) What is the magnitude of the normal force on the crate?
