Galileo is said to have dropped cannonballs from the Leaning Tower of Pisa to study gravity he drops a 5 kg ball from a height of 12 meters, how much potential energy will the have?

Respuesta :

Given data:

* The mass of the ball is m = 5 kg.

* The height of the ball is h = 12 m.

Solution:

The potential energy of the ball is,

[tex]U=\text{mgh}[/tex]

where g is the acceleration due to gravity,

Substituting the known values,

[tex]\begin{gathered} U=5\times9.8\times12 \\ U=588\text{ J} \end{gathered}[/tex]

Thus, the potential energy of the ball is 588 J
