A boat is moving 24.4m/s, 35 degrees North of East against the 10m/s water current that flows towards south. What would be the speed of the boat as it crosses the river

  • Physics -

    If we let +x be eastward, we have

    <19.98,13.99> or, approximately
    <20,14>
    Add that to <0,-10>
    and the resultant velocity is

    <20,4>
    The (eastward) speed with which the boat is crossing the river is 20m/s.

    Not sure whether I interpreted your language correctly, as it is somewhat ambiguous. If I got it wrong, fix the numbers and follow the steps.
