An object with a mass of #2 kg# is acted on by two forces. The first is #F_1= < -2 N , 8 N># and the second is #F_2 = < 4 N, -1 N>#. What is the object's rate and direction of acceleration?
The rate of acceleration is
The resultant force is
We apply Newton's second Law
The magnitude of the acceleration is
The angle is in the 1st quadrant

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.

- An object with a mass of #4 kg# is lying still on a surface and is compressing a horizontal spring by #1/4 m#. If the spring's constant is #3 (kg)/s^2#, what is the minimum value of the surface's coefficient of static friction?
- If a #2 kg# object moving at #80 m/s# slows to a halt after moving #9 m#, what is the coefficient of kinetic friction of the surface that the object was moving over?
- An object with a mass of #6 kg# is on a plane with an incline of #pi/12 #. If the object is being pushed up the plane with # 8 N # of force, what is the net force on the object?
- An object with a mass of #4 kg# is acted on by two forces. The first is #F_1= <1 N , 8 N># and the second is #F_2 = < 7 N, -8 N>#. What is the object's rate and direction of acceleration?
- A truck pulls boxes up an incline plane. The truck can exert a maximum force of #4,000 N#. If the plane's incline is #pi/3 # and the coefficient of friction is #1/3 #, what is the maximum mass that can be pulled up at one time?
