    Relative Motion: Solving for Time Elapsed for Boats A & B

    Hm. Okay, they don't have the same magnitude. And I think I understand why I need to consider them as vectors. So something along the lines of a(B/A)x = aBcos45 - aAcos60, the same in y direction, then find the magnitude of aB/A and use that?

    Relative Motion: Solving for Time Elapsed for Boats A & B

    We're always told that we should solve the problems symbolically first. So when I first tried, I just used it as in the formula with aB/A=aB-aA to find B relative to A. Im not exactly sure what you mean when you say I need to treat the accelerations as vectors. If you mean that I should...

    Relative Motion: Solving for Time Elapsed for Boats A & B

    Homework Statement The raceboats A and B leave at the same time the beach at point O with zero initial velocity. The path of boat A forms an angle of 60º with the beach and the path of boat B forms an angle of 45º. Both boats move with constant acceleration. Compute the time elapsed until the...
