• In the middle, a little closer to the top.

At which point would the skater have the most kinetic energy?

• A

• B

• C

• D

• E

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.

What kind of energy does the cannon ball have at Points A, C and E?
