1. Homework Statement

A mover pushes a 85kg crate along the floor at a constant speed through a displacement of 3,1m[E]. The coefficient of kinetic friction between the floor and crate is 0.22.

A) Calculate Fn and Fapp.

B] Calculate the work done by the mover.

3. The Attempt at a Solution

Fg=mg

=85kg*9.8N/kg

Fg=833N

So Fn=Fg

but how can i find Fapp

B] w=183N*3.1m

w=567.3
