Academics

Ship A is located 3.7 km north and 2.7 km east of ship B. Ship A has a velocity of 22 km/h toward the south and ship B has a velocity of 40 km/h in a direction 37° north of east.

(a) What is the velocity of A relative to B (Express your answer in terms of the unit vectors i and j , where i is toward 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 as above.

(d) What is that least separation?
