A mechanic uses a mechanical lift to raise a car. The car weighs 10,200 N. The work required to do this was 22,440 J.

What is the distance over which the force was applied?

What is the distance over which the force was applied?

anonymous · Answer

We know that work = Force * Distance.

What was the force used to lift the car?

22,440

anonymous · Answer

Given that work is:$$W=Fd$$where W is work; F is force; and d is distance, solve the equation for d.

anonymous · Answer

No, that was the work done. We need the force to lift the weight of the car. This will be the same as the weight of the car. Since we know the work, and the force, we can solve for d, the distance.

songbird2255 · Answer

We figured it out. The work was the distance, so the answer was 22,440 J

anonymous · Answer

That doesn't make any sense given the above information about the problem. Joules are a unit of work (and energy), and newtons are a unit of force.  Given the original numbers, the distance should be a lot smaller in magnitude, smaller by about 3 orders of magnitude.
