An object with a mass of 50 kg is being dragged along a horizontal floor by a horizontal force of 30 N. If the friction force opposing the motion is a steady 20 N, what is the acceleration of the body

• Physics -

sum(F) = m*a
where sum(F) is the sum of the forces, m is mass, and a is acceleration:

30 - 20 = 50*a
