Answer :
To find the mass of the roller coaster using the potential energy formula, we can follow these steps:
1. Identify the given values:
- Potential Energy (PE) = 235,200 Joules
- Height (h) = 30 meters
- Gravitational acceleration (g) = [tex]\(9.81 \, \text{m/s}^2\)[/tex] (standard acceleration due to gravity)
2. Use the potential energy formula:
[tex]\[
\text{Potential Energy (PE)} = m \times g \times h
\][/tex]
where [tex]\(m\)[/tex] is the mass we want to find.
3. Rearrange the formula to solve for mass ([tex]\(m\)[/tex]):
[tex]\[
m = \frac{\text{PE}}{g \times h}
\][/tex]
4. Plug in the known values:
[tex]\[
m = \frac{235,200}{9.81 \times 30}
\][/tex]
5. Calculate to find the mass:
To solve this, you divide 235,200 by the product of 9.81 and 30, which gives you approximately 799.18 kg.
Therefore, the mass of the roller coaster is approximately 800 kg.
