A man pushing a crate of mass m = 92.0 kg at a speed of v = 0.870 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 0.352 and he exerts a constant horizontal force of 285 N on the crate. (a) Find the magnitude and direction of the net force on the crate while it is on the rough surface. magnitude 32.36 N direction opposite as the motion of the crate (b) Find the net work done on the crate while it is on the rough surface. J (c) Find the speed of the crate when it reaches the end of the rough surface.
