A man pushing a crate of mass m = 92.0 kg at a speed of v = 0.855 m/s encounters a rough horizontal surface of length = 0.65 m as in the figure below. If the coefficient of kinetic friction between the crate and rough surface is 0.355 and he exerts a constant horizontal force of 295 N on the crate. v @ (a) Find the magnitude and direction of the net force on the crate while it is on the rough surface. magnitude[25.07 |y N direction o (b) Find the net work done on the crate while it is on the rough surface. 625 v 3 (c) Find the speed of the crate when it reaches the end of the rough surface.
