To find the force necessary to accelerate the object horizontally at 12 m/s^2, you need to use Newton's second law of motion: ( F = ma ). First, calculate the frictional force opposing the motion using the formula: ( f_{\text{friction}} = \mu_k \times N ), where ( \mu_k ) is the coefficient of kinetic friction and ( N ) is the normal force. Then, subtract the frictional force from the force required to accelerate the object. Finally, use the formula ( F = ma ) to find the net force.

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 # 18 kg# is lying on a surface and is compressing a horizontal spring by #60 cm#. If the spring's constant is # 18 (kg)/s^2#, what is the minimum value of the surface's coefficient of static friction?
- An object, previously at rest, slides #6 m# down a ramp, with an incline of #(3pi)/8 #, and then slides horizontally on the floor for another #8 m#. If the ramp and floor are made of the same material, what is the material's kinetic friction coefficient?
- A flower pot with a mass of 6.8kg is hanging by 4 wires that make an angle of 53° from the horizontal. If there were 7 wires connected to the pot instead of 4, what would the tension on each wire be?
- 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)/8, (3pi)/8], where x is in meters?
