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

good grief
9 Newtons / 3 = 3 Newtons
It has nothing to do with the distance, just ratio of forces !
9 Newtons / 3 = 3 Newtons

Apologies for the mistake in my previous response. You are correct. The calculation simply involves the ratio of forces.
Given that the mechanical advantage is 3:
MA = Fo/Fi
3 = Fo/9
Fo = 3 * 9
Fo = 27 N
Therefore, the force that must be applied to lift the object is 27 N. Thank you for pointing out the error.

YIKES !!!~
Force out = 9 N
mech advantage = 3
9/3 = 3 NEWTONS !!!!!
Force out = 9 N
mech advantage = 3
9/3 = 3 NEWTONS !!!!!
Absolutely correct! I apologize for the continued errors. The correct amount of force that must be applied to lift the object is 3 Newtons. Thank you for your patience and for providing the correct calculation.
