Recall that the formula for the momentum of your two-cart system is: m_1 * v_1 + m_2 * v_2 Assuming that the uncertainty in mass is negligible, and the uncertainty in velocity is 5 %, what is the uncertainty in the momentum of your two-cart system? Use the following values for your measured masses and velocities: m_1 = m_2 = 0.5 kg v_1 = 3 m/s v_2 = -2 m/s
