Solve the each part of given problem:
Problem: During a front-end car collision from 45.5 km/h and with air bags inflated, the acceleration limit for the chest is 60g as the car comes to rest. The trunk or chest area of the body comprises about 43% of body weight.
Part A: Draw a free-body diagram of a person during the crash centered on the origin of the axes. The diagram does not need to be drawn to precise scale. Assume the car is traveling from left to right along the x-axis. (x,y chart).
Part B: For how much time does this acceleration last, assuming it is constant at 60g?
Part C: What force in Newton's does the air bag exert on the chest of a 77.5 kg person?
I have tried this so many times and I cannot get the correct answer! Any help with steps will be great! Thank you!
