<u>Answer</u>
<em>The total displacement of the object is 320 m</em>
<u>Solution-</u>
From the formulas of mechanics,

Where,
s = displacement
u = initial velocity = 0 ( ∵ As the body was in rest in the beginning )
t = time taken = 8 s
a = acceleration = -10 m/s² ( ∵ -ve is because of the downward motion)
Putting all the values,
( ∵ -ve displacement means it is in downwards)
67% is bigger because (2/3) = 66.666667%
Hope this helps (:
Can you add a little bit more detail? Am I finding out how much the difference is or something?
I think it's 3.6 pounds of chicken
