A 5.20-kg wooden crate is being pulled up on an incline by a motor with a pulling force of 75.0 N. The coefficients of friction (static and kinetic) between the crate and the incline are μs = 0.75 and μk = 0.25, respectively. At the instant shown, the normal force, N, exerted by the incline on the crate is equal to 46.2 N, and θ = 25.0° Determine the magnitude and direction of the resultant of the friction force and normal
