1. Two forces are the only forces acting on a 2.8 kg object which moves with an acceleration of 3.8 m/s^2 in the positive y direction. One of the forces acts in the positive x direction and has a magnitude of 6.5 N.What is the magnitude of the other force f2? 2. Relevant equations F=ma 3. The attempt at a solution I suppose that to get the second force i just have to multiply F[SUB/]2[SUB/]=ma=(2.8kg)(3.8m/s^2) right?
