A car is traveling at 25m/s when an accident occurs. The car decelerates 300m/s^2 but the passenger does not slow down because he is not wearing a seatbelt. a) Supposing the distance between the passenger and the dashboard is initially 0.50m, what will be the speed of the car at the instant the passenger impasts the dash? b) The difference in speeds is the relative speed of the person's impact-what is this value? c) How far has the car moved forward at the instant of impact? How do I set this problem up?
