The time in seconds, t, it takes for a specific object being dropped from a particular height in feet above sea level, h, to reach the ground can be found by the radical function t equals one fourth times radical h period At what height should you drop an object in order for it to reach the ground in 8 seconds?

1,024 feet
256 feet
64 feet
4 feet

Respuesta :

Applying the function, it is found that the object was dropped from a height of 256 feet.

--------------------

The time it takes for the object to hit the ground is given by:

[tex]t(h) = \sqrt{\frac{h}{4}}[/tex]

--------------------

  • It took 8 seconds to hit the ground, thus, [tex]t = 8[/tex], and we have to solve for the height h.

[tex]t(h) = \sqrt{\frac{h}{4}}[/tex]

[tex]8 = \sqrt{\frac{h}{4}}[/tex]

[tex](\sqrt{\frac{h}{4}})^2 = 8^2[/tex]

[tex]\frac{h}{4} = 64[/tex]

[tex]h = 4(64) = 256[/tex]

The object was dropped from a height of 256 feet.
