Answer:

v = -2i - 20j

Step-by-step explanation:

Vector v is < 19 - 21, -8 - 12 >, or < -2, -20 >.  If the magnitude of u is five times that of v, then u = 5 · < -2, -20 >, or < -10, -100 >.

In summary, vector u is < -10, -100 > and vector v is < -2, -20 >.

In other words, vector v = -2i - 20j.     vector u is not needed here.
