Need help solving
A person wearing a seatbelt has a good chance of surviving a car crash if the magnitude of the deceleration is no more than 300 m/s2. Over what duration must a crash occur for the occupants of the car to survive being brought to a standstill from an initial speed of 100 km/hr?

Part AA person who is properly restrained by an over-the-shoulder seat belt has a good chance of surviving a car collision if the deceleration does not exceed 30 "g's" (1.0g=9.8m/s2).Assuming uniform deceleration at 30 g's, calculate the distance over which the front end of the car must be designed to collapse if a crash brings the car to rest from 70 km/h .Express your answer to two significant figures and include the appropriate units. Part B Determine the stopping distances...

The human body can survive an acceleration trauma incident (sudden stop) if the magnitude of the acceleration is 250 m/s2. If you are in an automobile accident with an initial speed of 113 km/hr (about 70 mi/hr) and you are stopped by an airbag that inflates from the dashboard, over what distance must the airbag stop you for you to survive the crash?

VU22475 Apply Scientific Principles to Engineering Problems Calculate the maximum deceleration of a car that is heading down a 8 slope (one that makes an angle of 8 with the horizontal). You may assume that the weight of the car is evenly distributed on all four tires and that the coefficient of static friction is involved - that is, the tires are not allowed to slip during the deceleration.
