Using the work-energy theorem, calculate the work needed to bring a car, moving at 90.0 m/s (~200 mph) and having a mass of 1200 kg, to rest. Next, if the car’s brakes supply a force of 8600 N resisting the motion, what distance will it take to stop? Hint: use the other work definition for second part.
Answer: −4,860,000 J, 565 m
