2. How does the gravitational potential energy of Coaster A compare with that of Coaster B?

An image shows two roller coasters. At the left, coaster A is positioned at the top of a 30 meter hill. To the right, coaster B is atop a 15 meter hill. (1 point)
The gravitational potential energy of Coaster A is twice as large as that of Coaster B.
The gravitational potential energy of Coaster A is half as large as that of Coaster B.
The gravitational potential energy of Coaster A is 15 times as large as that of Coaster B.
The gravitational potential energy of Coaster A is equal to that of Coaster B.

Is this for connexus?

@Barryallenakatheflash

Thanks ALOT!!!! :)

Barry allen aka the flash is correct, and yes, it's for connexus.

barry is wrong. 5/10!!!

I got one question?, Were do you get 243 from 54* 3? the correct answer is 162...

Thank you Barry Allen very much appreciated (โ˜ž อกยฐ อœส– อกยฐ)โ˜ž

Isn't Barry wrong?

To compare the gravitational potential energy of Coaster A and Coaster B, you need to understand the relationship between gravitational potential energy and the height of an object above the ground. The formula for calculating gravitational potential energy is P.E. = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.

In this scenario, you are given the heights of Coaster A and Coaster B. Coaster A is positioned at the top of a 30 meter hill, and Coaster B is positioned at the top of a 15 meter hill. Since the mass and acceleration due to gravity are the same for both coasters (assuming they have the same mass and are on the same planet), we can compare their potential energies based on their heights.

Using the formula, we can calculate the potential energy for Coaster A: P.E. = mgh = mg(30) = 30mg
And we can calculate the potential energy for Coaster B: P.E. = mgh = mg(15) = 15mg

Since the potential energy depends linearly on the height, we see that Coaster A's potential energy is twice as large as Coaster B's potential energy. Therefore, the correct answer is: "The gravitational potential energy of Coaster A is twice as large as that of Coaster B" (Option A).
