Question

the brakes on a car do 240000j of work in stopping the car. if the car travels a distance of 40m while the brakes re being applied. how large is the average force that the brakes exert the car?​

Answer 1

A joule is one Newton of force applied over a meter.
For every meter, the brakes put 240000N of force (N=Newtons).
For 40m, multiply the Newtons by 40.
240000N*40=9600000N
