Answer:

25 N

Explanation:

Use the equation F = m(Vf–Vi) / Δt.

average force = mass (final velocity - initial velocity) / change in time

F = 40 kg(5.0 m/s) / 8.0 s = 200 / 8.0 = 25 kgm / s^2 = 25 Newtons

Explanation:

I am pretty sure this will give you the general idea of one of the actions took by revolutionaries to allow some form of equality. I would suggest putting this general statement into your own words to avoid any issues just in case my answer isn't sufficient :)
