Homework Statement
A wagon friction fore is 60N when moving, same for any load its carrying. A horizontal force is applied of 150N causes wagon to be accerate at 5 m/s/s. The same force with a child in the wagon causes it to accerate at 1 m/s/s how do I answer this question to find mass of the child?
Homework Equations
M = F/A
The Attempt at a Solution
First I don't know to find the F in the above equation. I tried doing 150-60 got me 90. So I did the 90/1. Which is 90 kg. But I don't think I did this question correctly as I didnt use 5 at all and the mass of a child cannot be 90 kg. Did I answer it right?
Thanks!
