Suppose you observe a collision of an isolated system of two particles. A friend observes the same collision in a reference frame moving in the $+x$ direction with respect to yours. According to the Galilean transformation equations, on which aspects of the collision will you agree with your friend? (Answer T or F.)
-(c) On the value of the system's total $z$-momentum

The Galilean transformation does not affect the momentum along axes perpendicular to the relative motion of the reference frames, so both observers will agree on the value of the system's total $z$-momentum.
