Consider a system consisting of two moving objects (treat them as point particles). The first has a mass of \( 0.25 \mathrm{~kg} \) and moves with a velocity of \( 15 \mathrm{~m} / \mathrm{s} \) in what we'll call the \( +x \) direction. The second has a mass of \( 0.45 \mathrm{~kg} \) and moves at \( 12 \mathrm{~m} / \mathrm{s} \) at an angle of 40 degrees above the \( +x \) axis. What is the magnitude of the total momentum of the system? \( 8.6 \mathrm{~kg} \mathrm{~m} / \mathrm{s} \) \( 9.2 \mathrm{~kg} \mathrm{~m} / \mathrm{s} \) \( 74.2 \mathrm{~kg} \mathrm{~m} / \mathrm{s} \) \( 8.3 \mathrm{~kg} \mathrm{~m} / \mathrm{s} \) \( 3.4 \mathrm{~kg} \mathrm{~m} / \mathrm{s} \)
