A man pushing a crate of mass

m= 92.0 kg

at a speed of

v=0.855m/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 is0.350and he exerts a constant horizontal force of283Non the crate.A man pushes a crate labeledm, which moves with a velocity vectorvto the right, on a horizontal surface. The horizontal surface is textured from the right edge of the crate to a horizontal distancefrom 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
direction	---Select--- 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. m/s
