... ‘m’ is the mass, and ‘a’ is the acceleration. If you caught a bowling ball with 48 times the momentum in the same way that you caught the baseball (i.e., accelerate the ball to a stop at the same rate), according to the equation it would take 48 times the force to do this! Although you don’t have to ...
