## Homework Statement

If Vx = 6.80 units and vy = -7.40 units, determine the magnitude and direction of V-> (vector, the arrow is above the V).

## Homework Equations

and## The Attempt at a Solution

Should we use the following:

V magnitude = √ ( Vx^2 + Vy ^2) = √ (6.80^2 + (-7.40)^2) = 10 units

and for the direction: tan θ = Vy/Vx = (-7.40)/6.80 = -1.1

θ= -47.4 degrees below the x axis.

Would this be correct?

Thanks!
