Question

Help meeeeeeeeeee pleaseeeeeeeeeeeee!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

The dive lasted approximately
`\boxed{\sf 2.76}` seconds.

Explanation:

Given formula: h = 16t²

Where, t is time in seconds and h is the distance in feet traveled by a free-falling body or object.

According to the question,

Height of the cliff from which diver dives (h) = 122 feet.

By substituting the value of height in the formula we get:

`\rm \implies 122 = 16 {t}^(2) \\ \\ \rm \implies {t}^(2) = (122)/(16) \\ \\\rm \implies {t}^(2) = 7.625 \\ \\ \rm \implies t = √(7.625) \\ \\ \rm \implies t = 2.76 \: seconds`
