You are an engineer working for an amusement park. They have asked you to develop one of the fastest roller coasters in the U. S., but they also want it to be
cost efficient. Therefore, they do not want to have to use a lot of energy for
braking near the completion of the roller coaster ride. How would you develop
this ride so that it is still easy for to the amusement park guests to get on and off?
