Answer:

<h2>The rock hits the ground between 2 and 2.5 seconds.</h2>

Step-by-step explanation:

The given table is:

t            h(t)

0           20

0.5        18.8

1             15.1

1.5          9

2            0.4

2.5        -10.6

3           -24.1

The ground level is when h(t) = 0, which is between 0.4 and -10.6, because in that interval is included the zero. So, the problem is asking when does the rock hit the ground, referring to time. We just have to look for t-values for 0.4 and -10.6.

<em>Therefore, the rock hits the ground between 2 and 2.5 seconds.</em>

Answer:

The rock hits the ground between 2

seconds and 2.5

seconds after it is dropped.
