a passenger of mass of 70 kg traveling at 30m/s not wearing a seat belt cones to rest in 0.01 seconds in a car crash he hits the dashboard/windshield which has an area of 0.5 m.
calculate force, acceleration, and pressure
Homework Answers
Here negative Signe implies
that the Acceleration was in the opposite direction to the motion
of men, so the force was. Since pressure is scalar quantity, there
is no need to put any signs to it.

A 70 kg person is in a car crash in which they ran into a large tree. They were not wearing a seat belt, and there was no airbag. In panic, the person stiffened their two arms, stopping their body’s motion by pushing on the steering wheel. Each arm is 1 m long with a cross-sectional area of 4 cm2. Assume that the arm is 1 long bone. With what minimum speed did they have to be going at the...

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...

K.L., a 25-yr-old Korean American, was not wearing his seat belt when he was the driver involved in a motor vehicle crash. The windshield was broken, and K.L. was found 15 ft from his car. He was face down, conscious, and moaning. His wife and daughter were found in the car with their seat belts on. They sustained no serious injuries, but were upset. All passengers were taken to the emergency department (ED). K.L. states, “I can't breathe” and cries...
