Hi, Please help me out, i am desperate! the homework is due soon. i have done this problem alot and i still can't figure out how to get the correct answers of (a) -250m/s^2, 25.5, -2x10^4 N = -4500 lb. b) -50m/s^2, 5.1, -40000N = -900lb. Question: a car moving at 10 m/s (22.4 mi/h) strikes a stone wall. (a) The car is very rigid and the 80-kg driver comes to a stop in a distance of 20 cm. what is his average acceleration and how does it compare with the acceleration of gravity g? how much force acted on him? express this force in both newtons and pounds. (b) the car is so constructed that its front end gradually collapses on impact, and the driver comes to a stop in a distance of 100 cm. answer the same questions for this situation.
