We know the frictional force acts on a sliding object in such a way that it opposes the motion. In this question, the crate is already sliding. So the frictional force acts on the crate opposing its motion.
We can exert force on the sliding crate to stop it from sliding. So the force exerted by us will also oppose its current motion.
Thus we can say that the frictional force on the sliding crate and the force exerted by us on the crate act in the same direction.
Given,
Frictional force
Force exerted by us
