# How is the wind pushing the crate left in this exercise, is the force applied is downwards and to the right? Taken from Fundamentals of Physics.

I understand the theory and the resolution. What I don't understand is how what is happening in the diagram is possible. How is it that the wind is pushing downwards and to the right on a crate and it somehow slides backwards? I figure it's something to do with Newton's 3rd law and how the floor pushes back on the crate with a force of $$-F^\rightarrow$$. If so why is there no vertical acceleration?

• The crate is initially moving right to left although how and why it has a velocity is not explained. The wind is slowing the crate, not causing it to move right to left. Mar 22 '20 at 18:29

The crate is said to be displaced. There isn't an explanation for why its displacement occurs. Obviously it was given some impulse ($$F_{initial}\Delta t = m\Delta v$$) which gave the crate enough kinetic energy to move 3 meters while experiencing the the opposing force exerted by the wind.
There's no Newton's third law explanation for its displacement ($$\vec{d} = -3.0 m\, \hat{i}$$) relating to the force exerted by the wind.
