A rocket fires two engines simultaneously. One produces a thrust of 725 N directly forward, while the other gives a 513-N thrust at 32.4° above the forward direction. Find the magnitude and direction (relative to the forward direction) of the resultant force that these engines exert on the rocket.
The Attempt at a Solution
I tried finding the magnitude by doing 725+513(cos(32.4°)) and got 1158 N but for the answer it says its 1190 N. Did I do something wrong or is the book wrong? And I am not sure how to find the direction after I get the magnitude.
