To find the force required to accelerate the object, use the formula: ( F = m \cdot (a + g \cdot \mu_k) )
Where: ( F ) is the force, ( m ) is the mass of the object, ( a ) is the desired acceleration, ( g ) is the acceleration due to gravity (approximately ( 9.8 , m/s^2 )), ( \mu_k ) is the kinetic friction coefficient.
Substitute the values: ( F = 7 , kg \cdot (28 , m/s^2 + 9.8 , m/s^2 \cdot 7) )

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, previously at rest, slides #8 m# down a ramp, with an incline of #pi/4 #, and then slides horizontally on the floor for another #9 m#. If the ramp and floor are made of the same material, what is the material's kinetic friction coefficient?

- An object with a mass of #14 kg# is on a plane with an incline of # -(5 pi)/12 #. If it takes #12 N# to start pushing the object down the plane and #7 N# to keep pushing it, what are the coefficients of static and kinetic friction?
- A truck pulls boxes up an incline plane. The truck can exert a maximum force of #4,500 N#. If the plane's incline is #pi/8 # and the coefficient of friction is #4/3 #, what is the maximum mass that can be pulled up at one time?
