A man pushing a crate of mass m = 92.0 kg at a speed of v = 0.865 m/s encounters a rough horizontal surface of length l = 0.65 m as in the figure below. If the coefficient of kinetic friction between the crate and rough surface is 0.351 and he exerts a constant horizontal force of 286 N on the crate.A man pushes a crate labeled m, which moves with a velocity vector v to the right, on a horizontal surface. The horizontal surface is textured from the right edge of the crate to a horizontal distance l from the right edge of the crate.

(a) Find the magnitude and direction of the net force on the crate while it is on the rough surface.

magnitude _____N

opposite as the motion of the crate

same 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.
