Bob wants to push a crate horizontally with a force of 100N. If the coefficient of kinetic friction between the crate and the floor is 0.5 and the crate has a weight of 800 N, can he move the crate.

Okay that's the problem and I don't believe that 100N is enough force to push a crate of 800N. But even if my answer is wrong I'm not sure which equation to use to prove it.

When I take the kinetic friction of 0.5 and times it by the crate's 800N, I get 400N. Is this the way to show that 100N is not enough force to push this crate?
