We can use the formula:

Work = Force x Distance

where Work is given as 40 J, Distance as 4 m

Therefore, we can find the Force as:

Force = Work/Distance = 40 J/4 m = 10 N

Since the push is in the same direction as the motion of the crate, the force on the crate is also 10 N. Therefore, the best choice is B) 10 N.
