Consider an ideal pulley system. Pull one end of a rope downward by 1 meter with 50 N of force, and you'll lift a 200-N load a distance of ____________________.
A) 1 meter.
B) 0.5 meter.
C) 0.25 meter.
D) None of these.
For an ideal pulley system, Force x distance is the same for both ends.
To a larger weight wth less force than the weight, you move it less distance than you pull the other end
