needed help on these 3 questions that I don't quite understand. Can someone please explain to me how to solve the answer?
Use this scenario to answer questions 1-3:
A car crashes in a tree at a velocity -26.6 m/s. The passenger in the car is wearing a seat belt and is stopped in 2.2 seconds. The mass of the passenger is 50 kg.
1. According the Newton's first law, what will the passenger's motion tend to be during the crash?
2. What was the force acting on the passenger?
3. What was the action and reaction force acting on the seat belt?
I don't need the answers; if I could just please get an explanation on these. Thanks a million!! =]
