A man pushing a crate of mass m= 920kg at a speed of V = 0.865 me encounters a rough horizontal surface of length 6–065m as in the figure below. If the coefficient of kinetic friction between the crate and rough surface is 0.353 and he exerts a constant horizontal force of 284 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 direction --Select-- (b) Find the net work done on the crate while it is on the rough surface. (c) Find the speed of the crate when it reaches the end of the rough surface. m/s
