Mark is in a deep hole looking for treasure. he is standing 8 feet below the surface. he throws an old coin he found with an initial upward velocity of 22 ft/sec. how long until it lands outside the hole, having gone up and come back down? use the formula where h is the height of the coin in feet (relative to the surface) and t is the time in seconds since mark threw it. ignore air resistance and round your answer to the nearest tenth.

Option D is correct.

Step-by-step explanation:

We have been given a function:

We will find at h=0 to find the time it will take until it lands outside the hole, having gone up and come back down.

In the given function we will put h=0.

On solving the above equation we will get t

So, it will never happen we are getting time as imaginary value.

Hence, it will not make it outside the hole.

Therefore, option D is  correct.

the answer to this question is "motor unit"

answer is : muchas/tipicas

have a nice day!
