Answer:
<em>The building is 54.66 m tall</em>
Explanation:
<u>Free Fall</u>
It occurs when an object falls under the sole influence of gravity and do not encounter air resistance.
If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is
.
The distance traveled by a dropped object at time t is:
![\displaystyle y=\frac{gt^2}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%3D%5Cfrac%7Bgt%5E2%7D%7B2%7D)
The watermelon is dropped from a tower dorm and takes t=3.34 seconds to hit the ground.
The distance traveled in that time is the height of the building:
![\displaystyle h=\frac{9.8*3.34^2}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20h%3D%5Cfrac%7B9.8%2A3.34%5E2%7D%7B2%7D)
h = 54.66 m
The building is 54.66 m tall
