1. The problem statement, all variables and given/known data Here is the problem. 2. Relevant equations Va/b = Va - Vb 3. The attempt at a solution s - swimmer w - water Vw = 0.3m/s Vs/w = 2.5m/s therefore, Vs - Vw = 2.5m/s Vs - 0.3m/s = 2.5m/s Vs = 2.8m/s Now I am a bit confused at this point. It is asking which direction the swimmer needs to swim. What I have tried to do is draw 1 velocity vector pointing directly upward (the 0.3m/s one) and another pointing 38.66 degrees from the horizontal (I calculated that angle using the dimensions given). Am I on the right course to solving the problem, or am I completely wrong?
