Question

Two 1000 kg cars drive east; the first moving
at 45 m/s, the second at 30 m/s.
What is the magnitude of the total momen-
tum of the system?
Answer in units of kg · m/s

Answer 1

what's the formula for momentum?

Answer 2

mass times velocity

Answer 3

so each car has a mass, and each car has a velocity. the TOTAL momentum of the system must be equal to the sum of the 2 individuals

Answer 4

So I just add the two momentums? Even if they are going different ways

Answer 5

the problem says they're moving in the same direction

Answer 6

Oh ok I misunderstood the question somehow thanks :)
