Question 8

During a safety test, a road sweeper travels 34 m between the driver seeing a warning signal and the vehicle coming to rest. When the brakes begin to act, the vehicle's kinetic energy is 156 kJ. The brakes transfer 6000 J for every metre travelled while braking. What is the thinking distance?
