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?
• 9 N
• 8 N
• 72 N
• 81 N
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.
