Step-by-step explanation:
When the object hits the ground, h = 0.
0 = -21.962x + 114.655
x = 5.2
From the table, the object landed at x = 4.6 seconds. So the line of best fit predicts a time 0.6 seconds greater than actual.
The original height is when x = 0.
h = -21.962(0) + 114.655
h = 114.7
So the line of best fit predicts the object was dropped from a height of 114.7 meters. This is higher than the actual 100 meters.
At x = 3.5:
h = -21.962(3.5) + 114.655
h = 37.8
So the line of best fit estimates the object reached a height of 37.8 meters after 3.5 seconds.
We know that at x = 0, h = 114.7. This is more than 4 meters from the actual initial height of 100 m.
Therefore, the answer must be A.
