Task:To understand how gravity-driven coasters based
on work and energy.

Concepts:Observation, mathmatical skills, core concepts

Directions/Activity:
1.Calculate the work done on you when you were pulled up
the 303-foot diagonal incline loading area.
2.Six Flags Kentucky Kingdom claims a maximum speed of
63 miles per hour and a maxium vertical height of 154 ft.
Is this claim valid? Explain
3.On Chang, riders plummet from the highest hill of 154 feet
into a 121.6-foot vertical loop. Explain the energy transfer
durning this part of the ride(hill to low point to top of loop)
4.Set up an equation which compares the initial energy at the
hilltop to the energy at the top of the loop. How do these
calculated energy values compare? Explain the differences.

Extensions: Chang has a 4155 feet track. The cost of the ride
was $12 million. What was the cost for this ride?
