1. The problem statement, all variables and given/known data A model of an 80 kg man and one of a 25 kg child in a 1000 kg car and secured with seatbelts. The car was moving at 75kph as it crashed into a break wall.If the collision took 0.2s, calculate the average force exerted on each model by its seat belt . 2. Relevant equations f=ma 3. The attempt at a solution im really confused, im thinking that for the man: 80x20.8 (75000/3600), the divide by 0.2, so the force is 8333.3 newtons? Does the car's weight have anything to do with this?
