1. The problem statement, all variables and given/known data Three forces in the x-y plane act on a 2.6 kg mass: 13.3 N directed at 65°, 7.6 N directed at 160 °, and 10.1 N directed at 236° . All angles are measured from the positive x-axis, with positive angles in the Counter-Clockwise direction. Calculate the magnitude of the acceleration. 2. Relevant equations Fx = m*ax Fy - m*ay Newton's Second Law in the x and y direction, respectively. 3. The attempt at a solution I drew a picture on a scratch piece of paper, calculated x and y components of each vector, and then added x and y components of the resultant. Solving for acceleration, I got ax = 1.688 m/s^2, and ay = 7.808 m/s^2. How do I get the magnitude of the acceleration? Sorry for not being able to post my picture.
