If a 3 kg object has a momentum of 33 kg ms whats its velocity?

Momentum = (mass) x (speed)

  33 kg-m/s = (3 kg) x (speed)

Divide each side by  3 kg :

   (33 kg-m/s) / (3 kg) = speed

         11 m/s                = speed

(You asked for velocity, but didn't give us any information about the direction
in which the object is moving.  So we can only work with the speed.)

Ibelieve the answer is b

Because the sun is the biggest and if the sun orbits the earth we will be dead probably
