Fa roller coaster at six flags had a car with a mass of 400 kg and a velocity of 50m/s, calculate the kinetic energy of the roller coaster

Kinetic Energy = (1/2) (mass) (speed)²

KE = (1/2) (400 kg) (50 m/s)²

KE = (200 kg) (2500 m²/s²)

KE = 500,000 kg-m²/s²

KE = 500,000 Joules

KE = 1/2 Mega-Joule

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
