Answer:

17.15 m/s

Explanation:

This is a case of free fall, so we can use the next equation:

v_{f}^2=v_{i}^2+2gh

where

v_{f} is the final velocity

v_{i} is the initial velocity (0 in this case)

g is the acceleration of gravity 9.8m/s^2

and h is the height at wich the ballon was pitched.

So we have:

v_{f}=\sqrt{v_{i}^2+2gh} =\sqrt{0^2+2(9.8m/s^2)(15m)} =\sqrt{294m^2/s^2} =17.15m/s

The final velocity, the velocity of the ballon when it hits the ground is 17.15m/s.
