Ship A is located 3.5 km north and 2.4 km east of ship B. Ship A has a velocity of 24 km/h toward the south, and ship B has a velocity of 37 km/h in a direction 31° north of cast. Should the ship Captains be worried? Choose your coordinates so that north is the positive y-direction and east is the positive z-direction. a. At what time (in hours) the ships are at closest proximity to each other? b. What is the distance (in km) between the ships when they are the closest?
