Answer:
Maximum height, h = 7.2 meters
Explanation:
It is given that,
Initial velocity of the balloon, u = 12 m/s
At maximum its final velocity, v = 0
We have to find its maximum height. Let its maximum height is h. Using third equation of motion as :
[tex]v^2-u^2=2ah[/tex]
here a = -g
So, [tex]h=\dfrac{v^2-u^2}{-2g}[/tex]
[tex]h=\dfrac{-(12\ m/s)^2}{-2\times 10\ m/s^2}[/tex]
h = 7.2 meters
Hence, the maximum height of balloon is 7.2 meters.
