Accepted Answer
That all depends on the angle between the two forces.It could be anything between 1.3 m/s² in the direction of the larger force, if they're in opposite directions, all the way around to 6.04 m/s² in the direction of both of them if they're both in the same direction. That includes magnitudes between 1.3n and 6.04n directed somewhere between the two forces if they're in different, unrelated directions.

Total net force is 99+64 which is 163. Netforce = ma so 163 = 27 * a so acceleration is 6.04 m/s^2
