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

Solve for w in the equation w⁄5 = 25
Anarel [89]

we are given

\frac{w}{5} =25

Since, we have to solve for w

so, we will isolate w on anyone side

Multiply both sides by 5

5*\frac{w}{5} =5*25

w =5*25

w =125

so,
