A crate of mass m = 57.1 kg is on a horizontal surface. Assume there is no friction between the crate and the surface. Two forces with magnitude F = 38 N are applied to the crate, as shown. One force is horizontal, and the other makes and angle of ϕ = 37∘ with horizontal, as shown. 50% Part (a) Write an expression for the magnitude of the acceleration of the crate in terms of F, m, and ϕ. 50% Part (b) What is the magnitude of the acceleration of the crate in m/s2?
