An engineer wishes to design a roller coaster so that
the cars will not fall when they are at the top of their
circular path.
A 500 kg roller coaster car is designed to travel at 20
m/s at the top of the circle. The engineer wants to
make the circle as large as possible while still being
at least one quarter the maximum radius for safety
reasons. How large can the radius of the circle be?
