A simple machine increases the distance that a force needs to be applied from 3 meters to 27 meters, and the work done is 216 Joules. How much force is applied?

Question

• 9 N
• 8 N
• 72 N
• 81 N

Answer 1

The work done is given by the equation: work = force * distance.

In this case, the initial distance is 3 meters, the final distance is 27 meters, and the work done is 216 Joules.

Let's assume the initial force applied is F.

So, from the equation work = force * distance, we can write:

216 = F * 27

To solve for F, we divide both sides of the equation by 27:

8 = F

Therefore, the force applied is 8 Newtons.
