- Two students are assisting their teacher with a forcel/mpulse demonstration. One student sits on a large skate cart while the other student pushes him. Ignoring any effects of friction or air resistance, which of the following is true about the lotal momentum of this system? An object which is moving has zero momentum . This problem cannot be solved. The force multiplied by the time equals the mass multiplied by the change in velocity. It is greater before the collision than after the collision Momentum change equals Impulse multiplied by time, then divided by the force.
