a) Compute the impulse necessary to bring to rest the 50.0 kg driver of an automobile initially moving at 25.0 m/s. (b) Find the average force on the driver if the deceleration is accomplished gradually by the application of brakes over a 10.0 s interval. (c) Find the average force if the car is stopped in a collision that brings the driver’s seat to rest in 0.100 s, assuming the driver is restrained by a seat belt. What are the functions of seat belts and airbags in a collision?
