If you throw a ball horizontally while standing on roller skates, you roll backward with a momentum that matches that of the ball. will you roll backward if you go through the motions of throwing the ball, but instead hold on to it? explain. assuming you've answered them in terms of momentum conservation, answer them also in terms of newton's third law (or vice versa, if you answered already in terms of newton's third law).
