Answer:
The total energy, i.e. sum of kinetic and potential energy, is constant.
i.e. E = KE + PE
Initially, PE = 0 and KE = 1/2 mv^2
At maximum height, velocity=0, thus, KE = 0 and PE = mgh
Since, total energy is constant (KE converts to PE when the ball is rising),
therefore, KE = PE
or, 1/2 mv^2 = mgh
or, h = v^2 /2g = 13^2 / (2x9.8) = 8.622 m
Hope this helps.

Answer from Gauth math
Answer:
Elements that occupy the same column on the periodic table
Hot/ warm air is less dense than cold/cool air. Therefore warm/ hot air rises and cool/cold air falls in the atmosphere to create convection currents. The hot air balloon also uses this concept to fly. The air in the balloon is heated by the inbuilt flamer and when the air rises in temperatures (in comparison to ambient air temperatures) it becomes less dense and begins to rise. This raises the balloon into the atmosphere.
