# An object with a mass of #3 kg# is acted on by two forces. The first is #F_1= < -2 N , -3 N># and the second is #F_2 = < 7 N, 1 N>#. What is the object's rate and direction of acceleration?

The resultant force acting is

First find the resultant force acting:

The magnitude of the force is:

The magnitude of the acceleration is given by Newton's Second Law:

The direction of the acceleration will be given by:

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.

- What is Newton's first law?
- Why is the Newton's second law called the equation law?
- An object with a mass of #2 kg# is acted on by two forces. The first is #F_1= < -6 N , 1 N># and the second is #F_2 = < 4 N, 9 N>#. What is the object's rate and direction of acceleration?
- An object with a mass of #7 kg# is on a surface with a kinetic friction coefficient of # 8 #. How much force is necessary to accelerate the object horizontally at # 31 m/s^2#?
- An object with a mass of #6 kg# is hanging from a spring with a constant of #4 (kg)/s^2#. If the spring is stretched by #12 m#, what is the net force on the object?
