Answer:
6.64 seconds
Step-by-step explanation:
Given that:
Distance between roof of the terminal and ground = 709 feet
A bucket was dropped from the roof.
To find:
The time taken by the bucket to hit the ground?
Solution:
Distance traveled,
= 709 feet
Initial velocity of the bucket,
= 0 feet/sec (because initially it was at rest)
Acceleration of the bucket will be equal to acceleration due to gravity i.e.
or 32.1741 ![ft/sec^{2}](https://tex.z-dn.net/?f=ft%2Fsec%5E%7B2%7D)
Let the time taken is
seconds.
Formula for distance is given as:
![s = ut+\dfrac{1}{2}at^2](https://tex.z-dn.net/?f=s%20%3D%20ut%2B%5Cdfrac%7B1%7D%7B2%7Dat%5E2)
Putting all the values:
![709 = 0 (t) + \dfrac{1}{2}(32.1741) t^2\\\Rightarrow 1418 = 32.1741 t^2\\\Rightarrow t^2 = 44.07\\\Rightarrow t \approx \bold{6.64\ sec}](https://tex.z-dn.net/?f=709%20%3D%200%20%28t%29%20%2B%20%5Cdfrac%7B1%7D%7B2%7D%2832.1741%29%20t%5E2%5C%5C%5CRightarrow%201418%20%3D%2032.1741%20t%5E2%5C%5C%5CRightarrow%20t%5E2%20%3D%2044.07%5C%5C%5CRightarrow%20t%20%5Capprox%20%5Cbold%7B6.64%5C%20sec%7D)
The answer is c
you (4,4) and another point need to be double (2,-5) so the other point needs to add to (4,-10) so 4 + 0 is 4 and 4 + - 14 = 10
