If vx = 7.50 units and vy = -6.10 units, determine (a)the magnitude and (b)direction of v⃗ .

The magnitude of a vector is defined as the square root of its components squared.
 We have then that the magnitude is:
 v = root ((7.50) ^ 2 + (- 6.10) ^ 2)
 v = 9.67 units
 The direction of the vector is:
 x = Atan (vy / vx)
 x = Atan ((- 6.10) / (7.50))
 x = -39.12 degrees (measured from the x axis)
 
 v = 9.67 units
 x = -39.12 degrees (measured from the x axis)

Biased means unfair but that's all ik
