Take right as positive. At one instant, A has mass 6 kg and moves left at \(\displaystyle \frac{10m}{s}\); B has mass 4 kg and moves right at \(\displaystyle \frac{6m}{s}\).
Find A’s signed momentum in \(\displaystyle \frac{\mathrm{kg}m}{s}\).
Enter one exact number or fraction unless the question specifies rounding. Use the requested units and positive direction; enter the number without its unit. Angles here use degrees. Give full reasoning separately for written problems.
