In 1979, Dr. Hans Liebold of Germany drove a race car 12.6 kmwith an average speed of 404 km/h. Suppose Liebold applied thebrakes to reduce his speed. What was the car's final speed if -3.00MJ of work was done by the brakes? Assume the combined mass of thecar and driver to be 1.00 times 10 to the 3rd power kg.
