Aweightlifter holds a 1,700 n barbell 1 meter above the ground. one end of a 2-meter-long chain hangs from the center of the barbell. the chain has a total weight of 500 n. how much work (in j) is required to lift the barbell to a height of 2 m?

In physics, work is equal to the product of force and distance, given that the direction of force is the same with the direction of the distance.

W = Fd

The total force is 
F = 1,700 N + 500 N = 2,200 N
Now, if the question is the work needed to lift the barbell from the ground, the distance would be 2 m. Hence, the work would be

W = (2,220 N)(2 m) = 4,400 N·m or 4,400 J

Just divide the x axis (the top) by 2 or multiply the y axis (the bottom) by 2

For range i think it’s area
