(Answered) The driver of a 8100 kg car decides to double the speed

Academics

The driver of a 810.0 kg car decides to double the speed from 20.3 m/s to 40.6 m/s. What effect would this have on the amount of work required to stop the car, that is, on the kinetic energy of the car?

KE_i = Blank × 10⁵ J

KE_f =Blank × 10⁵ J

times as much work must be done to stop the car.
