Homework Statement
-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?
Homework Equations
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!
