1, Might not be precise
2, Can be hard to plot the graphs
3, If there are many solutions that will be really hard to plot sometimes.
This is just from the top of my head.
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
The answer is 14.33333 but you will have to round which you will just have 14.3
4:5 of 4 to 5 representing Miami Dolphins to Oakland Raiders
Volume = Length × Breadth × Height
So you are absolutely right, it is 252 yards squared
