Sort the following forces as relevant or not relevant to this situation. The symbols are defined as follows: normal force = n⃗ ,
tension force = T⃗ , horizontal force of the road on the car = F⃗ rc, horizontal force of the road on the truck = F⃗ rt, weight = w⃗ , force of the car pushing on the truck = F⃗ ct, and force of the truck pushing on the car = F⃗ tc.
