Ответ:
Explanation:we divided the truck weight by 2 since the front tires carry half the truck weight (the question tells us this). In part b) on the other hand, we're dealing with a metal cabinet in the truck box. The normal force applied by the truck box on the metal cabinet is the full weight of the cabinet, hence no need to divide by 2. The weight of the cabinet is being supported by only one thing, namely the truck box, whereas the weight of the truck is being supported by 2 sets of wheels, only one of which is applying static friction to the ground since we assume it's a front wheel drive truck.
