Question:

What is the work done by a cars braking system when it slows the 1500-kg car from an initial speed of 96 km/h?

I keep getting a number that is way to big. I have a final tomorrow and need help now! Thanks!

Answer:

Dear Sir, Please Kindly Check/rep Engines Vaccums And Throttle Position Sensor.
Why would auto autos do that? Why you give me so many points down? I don't know about auto auto transmissions, just like the OP.
You have just described every car with an automatic transmission. That's what they do.
96km/k 96/3.6 26.6 m/s Finally the car stops. All its initial energy has to be removed by the braking system. Its initial energy was 0.5mu? 0.5*1500*26.6? 530670 J . work done by a car's braking system 530670 J Though big it is needed for such a heavy kg . .
