# An object with a mass of #2 kg# is acted on by two forces. The first is #F_1= < -6 N , 2 N># and the second is #F_2 = < 6 N, 3 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 #6 kg# is pushed along a linear path with a kinetic friction coefficient of #u_k(x)= 1+cotx #. How much work would it take to move the object over #x in [(pi)/12, (3pi)/8], where x is in meters?
- Why do new shoes squeak?
- A crate with a mass of 12kg is sliding across the floor with a velocity of 8.8m/s. If the coefficient of kinetic friction is 0.16, how far will it slide before coming to rest?
- An object with a mass of #1 kg# is pushed along a linear path with a kinetic friction coefficient of #u_k(x)= 3x^2-x+2 #. How much work would it take to move the object over #x in [1, 3], where x is in meters?
- An object, previously at rest, slides #5 m# down a ramp, with an incline of #(pi)/6 #, and then slides horizontally on the floor for another #24 m#. If the ramp and floor are made of the same material, what is the material's kinetic friction coefficient?
