The velocity vector V1 has a magnitude of 4.0 m/s and is directed along the +x-axis. The velocity vector V2 has a magnitude of 3.0 m/s. The sum of the two is V3, so that V3 = V1+V2
A. The x-component of V3 can be 3.0 m/s
B. The magnitude of V3 can be 8.0 m/s
C. The magnitude of V3 can be 4.0 m/s
D. The magnitude of V3 can be -6.0 m/s
E The magnitude of V3 can be 0.0
F The magnitude of V3 can be 7.0 m/s

Its asking which if A-F are true or false.

  1. F. V3 = 4 + 3 = 7.
    To add them directly, both must be on the X-axis.
