What is the impulse delivered to the driver by the seat belt

Reference no: EM13717374

Solve the given parts of following problem:

Problem: When it crashes into a bridge support that does not move, a car goes from 110km/h to 0 in 1.23 m.

Part I: What is the impulse delivered to the 70-kg driver by the seat belt, assuming the belt makes the driver's motion identical to the car's motion? Assume that the initial direction of motion of the car is the positive direction.

Part II: What is the average force exerted by the belt on the driver?

Part III: If the driver were not wearing the seat belt and flew forward until he hit the steering wheel, which stopped him in 0.0145 s, what would be the average force exerted by the steering wheel on him?

I need expert help to solve the above problem and express your answer to two significant figures and include the appropriate units. Thanks.
