uỹ the person 10. The parachutist in the previous two exercises hits the ground (still wearing the previous two exercises hits the ground (still wearing the driver suffer serious injury? Assume constant deceleration of the driver's head after hitting the air bag. (Ans. GSI=420; no, the driver should not suffer during the deceleration? 10. The parachutist in the parachute!) and is stopped in a distance of 0.10 m. If this final deceleration is constant, calculate the Gadd severity impact of the landing. (Ans. GSI=370.) 11. A 75. kg person jumping from a 1.00×10³ m cliff will reach a terminal speed of 50. m/s and uses a 100. m bungee cord to slow the descent. The bungee cord exerts a force F proportional to its extension, where F (in newtons) = (5.0N/m) x (extension in m) and is designed to extend by 50.0m in the course of bring- ing the user to a stop just above the ground. Is the maximum deceleration in g experienced by the falling person more or less than the maximum deceleration experienced by a parachutist undertaking the same leap (excluding landing forces)? 12. An air bag is designed to inflate very quickly and subsequently compress ir the driver hits it. A collision uniformly stops a car from 30.0 mph to 0.00 and triggers the air bag. The driver is not seat-belted and so hits the inflated air bag. This acts as a local crumple zone and consequently compresses by 0.2o as his head is brought to rest. According to the Gadd severity index, does he driver suffer serious injury? Assume constant deceleration of the driver's fieae after hitting the air bag. (Ans. GSI=420; no, the driver should not sufter serious injury or death.) 13. Two 100. kg football players wearing %3D %3D met wuhil
