Question

The brakes on a car do 220,000 J of work in stopping the car. If the car travels a distance of 39 m while the brakes are being applied, what is the force the brakes exert on the car? Round to a whole number.

Answer 1

5641 N

Step-by-step explanation:

The force the brakes exert on the car can be found by using the formula

`f = (w)/(d) \\`

w is the workdone

d is the distance

From the question we have

`f = (220000)/(39) \\ = 5641.025641...`

We have the final answer as

5641 N
