A roller coaster with a potential energy of [tex]$235,200 J$[/tex] sits at the top of a 30 m high hill. What is the mass of the roller coaster? (Formula: [tex]PE = mgh[/tex])

A. 800 kg
B. 7,840 kg
C. 8,000 kg
D. 78,400 kg

Answer :

To find the mass of the roller coaster, we can use the formula for potential energy:

[tex]\[ PE = m \times g \times h \][/tex]

where:
- [tex]\( PE \)[/tex] is the potential energy, which is 235,200 Joules.
- [tex]\( m \)[/tex] is the mass of the roller coaster that we need to find.
- [tex]\( g \)[/tex] is the acceleration due to gravity, approximately 9.8 m/s².
- [tex]\( h \)[/tex] is the height of the hill, which is 30 meters.

Rearrange the formula to solve for the mass ([tex]\( m \)[/tex]):

[tex]\[ m = \frac{PE}{g \times h} \][/tex]

Now, substitute the given values into the formula:

[tex]\[ m = \frac{235,200}{9.8 \times 30} \][/tex]

First, calculate the denominator:

[tex]\[ 9.8 \times 30 = 294 \][/tex]

Now, divide the potential energy by this product:

[tex]\[ m = \frac{235,200}{294} \][/tex]

[tex]\[ m = 800 \][/tex]

So, the mass of the roller coaster is 800 kg.
