SUMMARY
The magnitude of vector V, given Vx = 6.80 units and Vy = -7.40 units, is calculated using the formula V magnitude = √(Vx² + Vy²), resulting in 10 units. The direction of vector V is determined using the tangent function, where tan θ = Vy/Vx, yielding θ = -47.4 degrees below the x-axis. This analysis confirms the calculations are accurate and provides a clear understanding of vector magnitude and direction.
