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

The rate of acceleration is

The force that results from this is

The rate of increase 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.

- Newton's second law states that the net force equals the product of mass and acceleration. A boat's mass of is #9.6×105 kg# and it experiences a net force of #1.5×104 kg*m/s^2#. What is its acceleration?
- What is the acceleration of the system and the tension in the ropes joining the masses in the following diagram?
- An object with a mass of #3 kg# is hanging from a spring with a constant of #8 (kg)/s^2#. If the spring is stretched by #1 m#, what is the net force on the object?
- How fast will an object with a mass of #16 kg# accelerate if a force of #32 N# is constantly applied to it?
- If an object is moving at #50 m/s# over a surface with a kinetic friction coefficient of #u_k=2 /g#, how far will the object continue to move?
