The Kingda Ka roller coaster at Six Flags Great Adventure (in New Jersey) is higher than the
Statue of Liberty at 456 feet tall. If the total mass of the cars is 537 kg and is treated as a point
mass, and if the cars had a velocity of 5 m/s at the top of the first hill, what would be the speed
of the roller coaster be at the bottom of that first hill? (ignore friction) (1 inch = 2.54 cm)
