Ship A is located 4.1 km north and 2.7 km east of ship B. Ship A has a velocity of 21 km/h toward the south and ship B has a velocity of 40 km/h in a direction 37° north of east. What are the (a) x-component and (b) y-component of the velocity of A relative to B? (Axis directions are determined by the unit vectors i Overscript ̂ EndScripts and j Overscript ̂ EndScripts, where i Overscript ̂ EndScripts is toward the east.) © At what time is the separation between the ships least? (d) What is that least separation?
