[SOLVED] Velocity Vectors

The velocity vector V1 has a magnitude of 3m/s and is directed along the +x-axis. The velocity vector V2 has a magnitude of 2m/s. The sum of the two is V3, so that V3 = V1+V2

A) The magnitude of V3 can be 0
B) The magnitude of V3 can be 6m/s
C) The magnitude of V3 can be 5m/s
D) The x-component of V3 can be -1m/s
E) The magnitude of V3 can be -4m/s
F) The magnitude of V3 can be 3m/s

Which are true and which are false?

I can't figure this out, if someone would even give me a hint... please I'd really appreciate it.

Start with the first one. Is there anyway those two vectors can add up to zero? Do you know what vector addition is?
