A car is traveling at 25 m/s when an accident occurs. The car decelerates 300 m/s2 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 0.50 m, what will be the speed of the car at the instant the passenger impacts the dash? (b) The difference in speeds is the "relatve speed" of the person's impact - what is this value? (c) How far has the car moved forward at the instant of impact. (d) At what minimum deceleration would the relative speed of impact be maximized?
