Mrs. Jackson gives the table below to her students. In order for the function to be linear, what must a be and why? a = 22 becau
se the rate of change is 1. a = 20 because the rate of change is 3. a = 22 because the rate of change is –1. a = 20 because the rate of change is –3.

<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)
