Trolley P has a mass of 2.0 kg and moves to the right at 3.0 m/s. Trolley Q has a mass of 1.0 kg and moves to the left at 3.0 m/s. What is the total momentum of the two trolleys?
3.0 kg m/s3.0\ \text{kg m/s}3.0 kg m/s to the left
3.0 kg m/s3.0\ \text{kg m/s}3.0 kg m/s to the right
9.0 kg m/s9.0\ \text{kg m/s}9.0 kg m/s to the left
9.0 kg m/s9.0\ \text{kg m/s}9.0 kg m/s to the right
