An object with a mass of 8 kg is acted on by two forces. The first is F_1= < -9 N , 2 N> and the second is F_2 = < -4 N, -3 N>. What is the object's magnitude and direction of acceleration?

The magnitude of acceleration is
And it makes an angle
Explanation:
The net force in x-direction is :
The net force in y-direction is :
The magnitude of the net force:
Thus the force makes an angle
Hence the magnitude of acceleration:
And the direction will be same as that of the net force.
