More About Magnitude of a Vector. 1  The magnitude of a unit vector is 1. 2  If V is the vector, we denote the length or magnitude of by |V|. | 3 V| = is the formula for finding the magnitude of the vector, where x and y are the components of the vector.
Integrating, we get the velocity vector v y (t) = v 1 i + (v 2 - 9.8t) j. Since the magnitude of our velocity is 100, we can say v y (0) = 100 cos q i + 100 sin q j. So that v y (t) = 100 cos q i + (100 sin q - 9.8t) j. Now integrate again to find the position function r y (t) = (100t cos q + r 1) i + (-4.9t 2 + 100t sin q + r 2) j
