The work done (W) is given by the formula:
W = Force × Distance
In this case, the work done is 440 Joules, and the distance is 4 meters. Therefore, we have:
440 = Force × 4
Simplifying the equation:
Force = 440 / 4
Force = 110 Newtons
So, a force of 110 Newtons must have been applied.
A lever with an effort arm of 10 meters and a load arm of 2 meters is used to lift an object weighing 220 Newtons to a height of 4 meters. Of 440 Joules of work is done, how much force must have been applied?
