Find the distance between each

between points (x1,y1) and (x2,y2)
D=\sqrt{(x2-x1)^2+(y2-y1)^2}



find and verify that
BC=CD=DE=EB

so
BC=\sqrt{(0-(-5))^2+(6-1)^2}=5√2
CD=\sqrt{(5-0)^2+(1-6)^2}=5√2
DE=\sqrt{(-4-1)^2+(0-5)^2}=5√2
EB=\sqrt{(-5-0)^2+(1-(-4))^2}=5√2

true

A weightlifter 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 ba
masha68 [24]
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
