Answer 1

A. According to the line of best fit, the object would have hit the ground 0.6 seconds later than the actual time the object hit the ground.

Explanation:

Answer 2

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.
