Question

If the roller coaster weighs 10,000kg and is traveling at 85 meters per second (m/s) what is the kinetic energy? Kinetic energy is measured in joules (j)?

Answer 1

36,125,000 Joule is the answer according to the formula KE=1/2×m×(v)2

Answer 2

36,125KiloJoules.

Step-by-step explanation:

K.E= 1/2MV².

that's 0.5 X 10,000 X 85.

which equals 36, 125, 000 Joules or 36,125 Kilo Joules.
