A pulley system has a mechanical advantage of 3, and an object weighing 9 Newtons must be lifted 15 meters. How much force must be applied to lift the object?
Use the following equation to find the answer:
MA=Fo/Fi

MA = Fo/Fi
We are given that the mechanical advantage (MA) is 3. Let's substitute this value into the equation:
3 = Fo/Fi
To find the force required to lift the object, we need to isolate Fo. Multiplying both sides of the equation by Fi:
3 * Fi = Fo
Now, we need to find Fi. We are given that the object weighs 9 Newtons and it needs to be lifted a distance of 15 meters. To find Fi, we can use the formula:
Fi = weight * distance
Fi = 9 N * 15 m
Fi = 135 N
Now, we can substitute Fi into the equation:
3 * 135 N = Fo
Fo = 405 N
Therefore, the force required to lift the object is 405 Newtons.
