Answer:

40 N

Explanation:

Newton's second law of motion states that the net force acting on the crate is equal to the product between its mass and its acceleration:

\sum F = ma

where

m is the mass

a is the acceleration

In this problem, we have:

- The net force can be written as

\sum F = F - F_f

where

F = 40 N is the horizontal forward push

F_f is the force of friction

Also, we know that the crate moves at constant velocity, so its acceleration is zero:

a=0

By combining all the equations together, we find:

F-F_f=0\\F_f = F = 40 N

So, the force of friction is 40 N.
