Physics, Help Greatly Appreciated?

Question

hey if anyone can help me with these problems, id greatly appreciate it

1.Two 1.5 Kg balls move away from each other, one traveling 5 m/s to the right, the other 5 m/s to the left. What is the magnitude of the total momentum of the system? in terms of Kg X m/s?
2. Two 1300 kg cars drive east: the first moving at 30 m/s, the second at 45 m/s. What is the magnitude of the total momentum of the system? in terms of Kg X m/s?
3. What is the momentum of a two particle system composed of a 1300 kg car moving east at 60 m/s and a second 1300 kg car moving west at 15 m/s. Let east be the positive direction. Answer in terms of KG X m/s

Answer 1

1.
(1.5 kg)(5 m/s) + (1.5 kg)(- 5 m/s) = ?
2.
(1300 kg)(30 m/s) + (1300 kg)(45 m/s) =
(1300 kg)(75 m/s) = ?
3.
(1300 kg)(60 m/s) + (1300 kg)(- 15 m/s) = ?

Answer 2

Sorry on your success, yet bill did no longer extremely answer #a million, and his answer for #2 is misguided. for 2, he used diameter extremely of radius. in basic terms plug in for this reason, could paintings out.
