Question

The table relates to a function h(t) that models the height of a rock t seconds after it is dropped.

A 2-column table with 5 rows. The first column is labeled t with entries 0, 0.5, 1, 1.5, 2, 2.5, 3. The second column is labeled h(t) with entries 20, 18.8, 15.1, 9, 0.4, negative 10.6, negative 24.1.
When does the rock hit the ground?

The rock hits the ground between
seconds and
seconds after it is dropped.

Answer 1

The rock hits the ground between 2 seconds and 2.5 seconds after it is dropped.

(h(2)=0.4>0 and h(2.5)=-10.6<0, so the height crosses 0 between those times.)
