# An object with a mass of #4 kg# is acted on by two forces. The first is #F_1= < -5 N , 2 N># and the second is #F_2 = < 1 N, 6 N>#. What is the object's rate and direction of acceleration?

The rate of acceleration is

The resultant force is

we use Newton's second Law

The magnitude of the acceleration is

But the angle is in the 2nd 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.

- How fast will an object with a mass of #24 kg# accelerate if a force 96 N# is constantly applied to it?
- How fast will an object with a mass of #16 kg# accelerate if a force of #14 N# is constantly applied to it?
- An object, previously at rest, slides #1 m# down a ramp, with an incline of #pi/12 #, and then slides horizontally on the floor for another #4 m#. If the ramp and floor are made of the same material, what is the material's kinetic friction coefficient?
- If the length of a #47 cm# spring increases to #57 cm# when a #8 kg# weight is hanging from it, what is the spring's constant?
- If the length of a #25 cm# spring increases to #67 cm# when a #15 kg# weight is hanging from it, what is the spring's constant?
