## Step-by-step instructions.

*Try to complete each section on your own before you move to the next image. Each slide shows the answer to the preceding question.*

### 1. First, examine the problem and determine the energy storage types involved.

This problem consists of a roller coaster which has a chain that pulls the car to the top of the first hill. The problem defines the system as frictionless (μ = 0), and insignificant air resistance.

*Before you go on, define the system, then draw axes for your energy diagrams at each point with a letter (don’t worry about the number of blocks of each energy storage yet).* Continue reading “Solving ‘roller coaster’ energy problems”
