Physics Question about 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


(For each statement select T-True, or F-False; If the first is True and the rest F, enter TFFFFF).





A) The magnitude of V3 can be 0


B) The magnitude of V3 can be 2m/s


C) The magnitude of V3 can be -2m/s


D) The magnitude of V3 can be 6m/s


E) The x-component of V3 can be 0m/s


F) The magnitude of V3 can be 5m/s

Physics Question about vectors!?
The largest that V3 can be is 5 m/s, if V2 is also in the positive x direction. The smallest it can be is 1 m/s, if V2 is in the negative x direction. Its magnitude can also have any value between 1 m/s and 5 m/s (if V2 makes some angle with the x axis).





A. False.


B. True.


C. False.


D. False.


E. False.


F. True.
