1. The problem statement, all variables and given/known data driving his homemade submarine underwater in a nearby lake. His instruments tell him that the sub is traveling at 8 m/s relative to the surrounding water and that the sub is oriented due north (nose pointing north). After two minutes, however, he ends up crashing into a sunken pirate ship. He is confused because he knows from his sonar that the pirate ship is located at a position 25° E of N, 600 m from his original position. The only explanation, he reasons, is that an underwater current must have caused him to drift off course. Calculate the speed and direction of the underwater current. 2. Relevant equations I'm assuming I need to find acceleration so I used X=Vit+.5at2 3. The attempt at a solution I got -0.05m/s2 which I'm pretty sure is wrong.
