FnetH=Fwinch -force of kinetic friction
We put force of winch first because it is the strongest force since the crate is moving in the direction of the winch.
FnetH= 2000N-uk(Fn)
FnetH=2000N-(0.2)(9800)
FnetH=2000N-1960N
FnetH= 40N
Fn=(9.8)(1000)= 9800N
9.8 m/s^2 earths gravitational acceleration.
uk=coefficent of kinetic friction=0.2
Fn= normal force.
