Question

day 1
wayne is riding on a roller coaster. the roller coaster travels up and down a large hill at first and then travels through several more smaller hills.
part a: at which point (a, b, c, d or e) does the roller coaster have the most potential energy? __________
part b: why does the roller coaster have the most potential energy at this point?

Explanation:

Part A

Step1: Recall Potential Energy Formula

Gravitational potential energy is given by \( PE = mgh \), where \( m \) is mass, \( g \) is acceleration due to gravity, and \( h \) is height.

Step2: Compare Heights at Points

Among points A, B, C, D, E, point A is the highest. Since \( m \) and \( g \) are constant, higher height means more potential energy.

Gravitational potential energy (\( PE = mgh \)) depends on height (\( h \)) (mass \( m \) and gravity \( g \) are constant here). Point A is the highest among A, B, C, D, E, so it has the most potential energy.

Answer:

A

Part B
