  3. Hint: Use the Pythagorean Theorem.
     
  4. I used it and got 11,624.97312. I entered 11,624.97 into Webassign and it came out a wrong answer. Could someone tell me if this is the right answer and im entering it wrong or if I completely did this wrong?

    I found one leg of the small triangle at the top of the diagram by subtracting 4900-3200, and used X1 as the other leg..then uesd the pythagorean theorem.
     
  5. nevermind, got the answer, thanks a lot. I've got another mechanics question if anyone's around.
