Question

If a monkey of mass 8 kg climbs up a tree and the tree is 10 meters high, then the potential energy of the monkey at the top of the tree will be 784 J.

true or false

Answer 1

Let's find the PE of the monkey at the top of the tree:

$$PE=mgh,$$ $$PE=8\ kg\cdot9.8\ \dfrac{m}{s^2}\cdot10\ m=784\ J.$$

Answer:

$PE=784\ J,$ true.
