(a) Compute the impulse necessary to bring to rest the 53.0 kg driver of an automobile initially moving at 20.0 m/s.
(b) Find the average force on the driver if the deceleration is accomplished gradually by the application of brakes over a 12.1 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.
