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 (1 point) Responses
3 N
27 N
0.3 N
1.7 N
MA = Fo / Fi
Given: MA = 3, Fi = 9 N
3 = Fo / 9
Fo = 3 * 9
Fo = 27 N
Therefore, the force that must be applied to lift the object is 27 N.
