A sailboat is sailing due east at 5.40 mph. The wind appears to blow from the southwest at 13.4 mph. 1. What is the true wind speed? 2.What is the true wind direction? ( south of west). 3.What is the true wind speed if the wind appears to blow from the northeast at 13.4 mph? 4.What is the true wind direction ( north of east) if the wind appears to blow from the northeast at 13.4 mph? I tried solving the first question but did not get the correct answer. I know if you get the first question right it is easy to solve the second. Here's what I tried sqrt ((13.4*sqrt (2)- 5.4)^2 + (13.4* sqrt(2))^2))= 23.29 mph but it wasn't right this is Ax part this is Ay part after finding the Ax and Ay just plug into equation: theta=arctan(Ax/Ay) PLEASE HELP ASAP NEED BY TONIGHT!!!!!
