The Attempt at a Solution
Okay, I think I can easily get the answer if I know what this question is asking me. By real velocity, Does it mean the displacement from point 100 m/s (N20E) to 40 m/s (S20E)? Like, I can draw it on a graph and make the triangle. I would then calculate the angle and length of the unknown side. If that's not it, Then how would I go about getting it? Please Help me understand this.
