Vector addition problem needs help

Click For Summary
SUMMARY

The discussion focuses on the vector addition problem involving two velocity vectors, V1 and V2, where V1 has a magnitude of 4 m/s along the +x-axis and V2 has a magnitude of 3 m/s. The resultant vector V3 is calculated as V3 = V1 + V2. The participants confirm that the only true statement regarding the magnitude of V3 is that it can be 7 m/s, while all other statements about V3's magnitude being 0, -4 m/s, 8 m/s, or 3 m/s are false.

PREREQUISITES
  • Understanding of vector addition
  • Familiarity with basic physics concepts of velocity
  • Knowledge of vector components

The velocity vector V1 has a magnitude of 4m/s and is directed along the +x-axis. The velocity vector V2 has a magnitude of 3m/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 7m/s
B) The x-component of V3 can be 0m/s
C) The magnitude of V3 can be -4m/s
D) The magnitude of V3 can be 0
E) The magnitude of V3 can be 8m/s
F) The magnitude of V3 can be 3m/s

i hate these tyes of problems can someone please help me out

Tell us what you have tried so far. The math is only addition and subtraction, so your problem begins by finding out what a vector is. You got a textbook?
