Question

What is the potential energy of an apple that 3.00-meters high with a mass of .5N?

Answer 1

Given:

Height, h = 3.00 meters

Mass, m = 0.5 N

Let's find the potential energy.

To find the potential energy, apply the formula:

$PE=m\times g\times h$

Where:

• m is the mass in kilograms

,

• g is acceleration due to gravity = 9.8 m/s²

,

• h is the height in meters

Let's convert the mass from Newtons to kilograms.

$\frac{0.5N}{9.8}=0.05kg$

The mass in kilograms is 0.05 kg.

Thus, to find the potential energy, we have:

$\begin{gathered} PE=0.05\times9.8\times3 \\ \\ PE=1.47\text{ J} \end{gathered}$

Therefore, the potential energy of the apple is 1.47 Joules.

ANSWER:

1.47 Joules
