Question

Equation Given:
`h(t)=-4.9t^(2)+358`

Question: When is the penny at a height of 300 meters above the ground?

Answer 1

At 3.44 seconds, the penny is at a height of 300 meters above the ground.

Explanation:

Basically, we have to solve an equation here:

`-4.9t^(2) + 358 = 300`

Hence,

`-4.9t^(2) = 300 - 358`

`t^(2) = (-58)/(-4.9)`

`t = 3.44`

Hence, at 3.44 seconds, the penny is at a height of 300 meters above the ground.

Hope this helped!
