Question

In science class the students were asked to create a container to hold an egg. They would then drop the container from a window that is 25 feet above the ground. If the equation of the containers pathway can be modeled by the equation h=-16t+25 how long will it take the container to reach the ground

Answer 1

It will take 1.25 seconds to reach the ground.

Explanation:

The equation of the containers pathway can be modeled by the equation given below :

`h=-16t^2+25`

t is time in seconds

It is required to find the time taken by the container to reach the ground. When it reached ground, its height is equal to 0 such that,

`h=0\\\\-16t^2+25=0`

`-16t^2=25\\\\t=\sqrt{(25)/(16)} \\\\t=1.25\ s`

So, it will take 1.25 seconds to reach the ground.
