A thermometer falls from a weather

Nesterboy [21]

Answer:

It will take 22 seconds for the thermometer to hit the ground.

Step-by-step explanation:

A thermometer falls from a weather balloon at a height of 7,744 ft.

This means that the initial height is of 7744ft.

h(t) = -16t2 + initial height

$h(t) = -16t^2 + 7744$

How many seconds will it take for the thermometer to hit the ground?

This is t for which $h(t) = 0$ . So

$0 = -16t^2 + 7744$

$16t^2 = 0 + 7744$

$t^2 = \frac{7744}{16}$

$t = \sqrt{\frac{7744}{16}}$

$t = 22$

It will take 22 seconds for the thermometer to hit the ground.
