If the larger boulder has a mass of 50 kg and a height of 150 m from the ground what is its GPE?

see other post.

73,500

To calculate the gravitational potential energy (GPE) of an object, you need to use the formula:

GPE = mgh

Where:
m = mass of the object (in kilograms)
g = acceleration due to gravity (which is approximately 9.8 m/s^2 on Earth)
h = height of the object from a reference point (in meters)

In this case, the mass of the larger boulder is given as 50 kg, and its height from the ground is 150 m. Therefore, we can substitute these values into the formula:

GPE = (50 kg) * (9.8 m/s^2) * (150 m)

Now, let's calculate the GPE using this formula:

GPE = 73500 J (joules)

So, the gravitational potential energy of the larger boulder is 73500 joules.
