(a) Compute the impulse necessary to bring to rest the 48.0 kg driver of an automobile initially moving at 20m / s? b) Find the average force on the driver if the deceleration is accomplished gradually by the application of brakes over a 11.6 s inteval? (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?
