Consider a car crash in which the vehicle travels at 13 m/s (roughly 30 mph) just before the collision. Research indicates that the passenger typically experiences an acceleration of 30 g's during such a crash if their seatbelt is fastened.

Vox = -13 m/s m, = 75 kg A) What is the duration of the collision, At? B) Calculate the passenger's kinetic energy before impact. What is the kinetic energy of this same passenger when jogging at a modest speed of 5 m/s?
