The brakes on a car exert a frictional force of 6,000 N in getting the car to stop. If the work done by the brakes is 120,000 J in coming to a stop, how many meters did the car travel after the driver applied the brakes?

Answer :

Answer: 20m

Explanation:

Use equation

A=F*s

F=6000N

A=120000J

-----------------------------

s=A/F

s=120000J/6000N

s=20m

Final answer:

The brakes on the car exert a force of 6000 N to stop the car. Using the work performed by the brakes, which is 120,000 J, and the equation for work (Work = Force x Distance), we can find that the car traveled 20 meters after the brakes were applied.

Explanation:

This problem can be solved using the basic physics equation for work: Work = Force x Distance. Here, the work performed by the brakes is given as 120,000 J, and the force exerted by the brakes is 6,000 N. We need to find how far (the distance) the car traveled after the brakes were applied.

To find the distance, we simply need to rearrange the equation: Distance = Work / Force. So, the distance traveled by the car is 120,000 J / 6,000 N = 20 meters.

This means the car traveled 20 meters after the brakes were applied to come to a complete stop.
