1. The problem statement, all variables and given/known data -Ship A is located 4 km north and 2.5 km east of ship B -ship A has a velocity of 22km/h south -ship B has a velocity of 40km/h in a direction 37 degrees north of east a) Find the velocity of A relative to B in unit vector notation, with i towards the east b) Write an expression in terms of i and j for the position of A relative to B as a function of t, where t = 0 when the ships are in the positions described above c)at what time is the separation between the ships least? d) What is that least separation? 2. Relevant equations 3. The attempt at a solution I believe the answer to part a, is V(A) = -22j I have absolutely no idea how to do b, c, or d Please do not solve the question for me, but if someone could point me in the right direction, it would be GREATLy appreciated!
