Vector has a magnitude of 12.5 units and points due west. Vector points due north.

Question

(a) What is the magnitude of if + has a magnitude of 17.7 units?

Answer 1

This makes no sense " of if+ has a"

If the question is what is the magnitude of the N vector if the resultant is 17.7, then

17.7^2=12.5^2+N^2
