Question

3 in which position would potential energy be the greatest? a w b x c y d z

Explanation:

Step1: Recall potential - energy formula

The gravitational potential energy formula is $U = mgh$, where $m$ is mass, $g$ is the acceleration due to gravity, and $h$ is height. Assuming the mass of the object on the roller - coaster and the value of $g$ are constant, potential energy depends only on height.

Step2: Compare heights

By observing the roller - coaster track, position $W$ has the greatest height among positions $W$, $X$, $Y$, and $Z$.

Answer:

A. W
