The rocket will take a time of approximately 2.686 seconds to hit the ground.
<h3>How much time does a rocket need to hit the ground?</h3>
The height of the rocket (h), in feet, is modelled by a quadratic equation, which is used to model free fall motion, that is, the motion of an object solely due to action of gravity. In this problem we must look for the time when the rocket hits the ground:
- 16 · t² + 40 · t + 8 = 0
(t - 2.686) · (t + 0.186) = 0
Only the first root offers a realistic solution, for time is a non-negative variable. The rocket will take a time of approximately 2.686 seconds to hit the ground.

The Problem which talks about correlation about Researchers studying senior citizens discovered that an elderly person's walking speed was correlated to that person's chance of living longer.
Also, it is given that The fastest walkers were more likely to live another 10 years than were the slowest walkers.
So, we can conclude from above statement that , elders who walks more has high correlation than the elders who do not take regular walk daily.
Yes, as walking makes our heart , body and mind strong, so chances of living becomes higher.
So, Elders who take walk regularly has high value of Positive correlation than person who does not take regular walk.
