Question

practice it!
an image of a roller coaster track and cart is
shown.
which of the following labels has the greatest
potential energy?
d
c
a
b

Explanation:

Step1: Recall the formula for gravitational potential energy

The formula for gravitational potential energy is \(U = mgh\), where \(m\) is mass, \(g\) is the acceleration due to gravity, and \(h\) is the height.

Step2: Compare the heights of points A, B, C, and D

Since \(m\) and \(g\) are constant (assuming the mass of the cart \(m\) is constant and \(g\) is constant for a given location), the potential energy \(U\) depends only on the height \(h\). Looking at the roller - coaster track, point A is at the highest elevation among points A, B, C, and D.

Answer:

A. A
