F= mxa
m=F/a
1. A little boy pushes a wagon with his dog in it. The mass of the dog andwagon together is 50 kg. The wagon accelerates at 0.85 m/s2. What force
is the boy pulling with?

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 50 × 0.85

We have the final answer as

Hope this helps you
