An object with a mass of #4 kg# is acted on by two forces. The first is #F_1= < -6 N , 3 N># and the second is #F_2 = < 6 N, 5 N>#. What is the object's rate and direction of acceleration?
The acceleration is
When you want to sum two vectors in classical mechanics, it is enough if you sum them component by component.
The final vector is
The length of a vector is given by that of our vector is Then the force is with a magnitude of 8N and the acceleration is given by The direction is given by This of course is a problem because we cannot divide by zero. On the other hand we know that the arctan is singular when the angle is

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
