What is the kinetic energy of a go kart with a mass of 150 kilograms and a speed of 20 m/s?

Kinetic Energy = 1/2mv^2

Kinetic Energy = 1/2(150 kg)(20 m/s)^2

Kinetic Energy = 75 kg(400 m/s)

Kinetic Energy = 30000 J

Let me know if this helps!

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
