Katy wants to design a roller coaster where the passenger is traveling super fast at the bottom. What characteristics should the roller coaster have?

• It should be flat and close to the ground. This way the passenger will have an increase in speed because he/she starts out close to the ground.

• It should have no friction and the passenger should start off high above the ground. This way the passenger starts out with a lot of potential energy that can be transformed into kinetic energy.

• It should have lots of friction and be very tall. This way the passenger will speed up because of the large amount of friction.

• It doesn’t matter how you design the rollercoaster the passenger’s speed will be the same at all points on the rollercoaster.
