Boat A and B

  1. May 2, 2009 #1
    Boat A's position is given by the parametric equation x=3-t, y= 2t -4 where position is km and time is hours. Boat B's poisiton is given by x=4-3t, y= 3-2t

    a) find the initail position of each boat
    b) find the velocity vector of each both
    c) what is the angle between the paths of the boat
    d) at what time are the boats closest to each other

    I have NO CLUE on how to start the question

    No clue? That's bad news. For a) try putting t=0. The bad news is that it gets more complicated after that. For b) and d) you have to differentiate. Can you at least try?
