A mass of 5 kg lies on a frictionless, horizontal floor. A force of 135 Newtons is applied to the mass at an angle above the positive x axis and a force of 14 Newtons is applied to the mass at an angle of 22.8 degrees below the negative x direction (see sketch). If the angle for 135 Newtons is increased until the object just starts to leave the surface, what is the magnitude of the acceleration on the mass in m/s2 at this point?
