A student watched a person fire an old cannon. The student noticed the cannonball moved with a very high velocity to the right and the cannon moved very slowly to the left.
Which statement BEST explains the student's observations?
The total momentum of the system was zero before the cannon was fired. Since momentum was conserved, the cannonball's momentum and the cannon's momentum must have been equal in magnitude but opposite in direction
