Question

A man pushing a crate of mass

m = 92.0 kg

at a speed of

v = 0.875 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 0.350 and he exerts a constant horizontal force of 297 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
direction	---Select---

(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
