Answer 2

Answer:

The roller coaster has potential energy of approximately 94,341 Joules.

Explanation:

We know,

Roller Coaster Potential Energy.

The potential energy of an object at a certain height above the ground is given by the formula:

Potential energy = mass × gravity × height

where mass is the mass of the object, gravity is the acceleration due to gravity (9.81 m/s² on Earth), and height is the height of the object above the ground.

In this case, the roller coaster is at the top of a 72 m hill and has a mass of 134 kg.

So, mass = 134 kg and height = 72 m.

Therefore, its potential energy can be calculated as:

Potential energy = 134 kg × 9.81 m/s² × 72 m

= 94,340.88 Joules

Therefore, the roller coaster has potential energy of approximately 94,341 Joules.
