What is the kinetic energy of a 400kg house that is racing around a track at 17 meters per second?

Respuesta :

20-02-2020

Kinetic energy = (1/2) (mass) (speed squared)

Kinetic energy = (1/2) (400 kg) (17 m/s)²

Kinetic energy = (1/2) (400 kg) (289 m²/s²)

Kinetic energy = 57,800 Joules

(That's some amazing house. I'd like to be there to see it.)
