Equal forces or balances forces cancel each other out. One side would have to have more force to move in the direction of least force.
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)
<em>Kinetic energy = 57,800 Joules</em>

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