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

Which is True ?
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 ones do you think are true?
 
C and D, but i know it's wrong... i just don't understand velocity vectors.
 
i think its C
 
there can be more than one answer, and i still can't figure it out...any help?
 
take a look http://www.glenbrook.k12.il.us/GBSSCI/PHYS/Class/vectors/u3l1b.html" if you don't know how to add two vectors.
