... Since the crate is doing uniform motion (constant velocity), acceleration a=0. According to Newton’s 1st Law, if a⃗⃗ = 0, ∑ ⃗F⃗ =0. In the horizontal direction, there are only two forces acting on the crate: the exerted 50N force and the unknown frictional force. These two must add up to be 0. So th ...
