The normal force is calculated by multiplying the coefficient of kinetic friction (0.03) by the gravitational force acting on the object. If the object's mass is 10 kg, the normal force would be approximately 294 N.

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.

- A box with an initial speed of #7 m/s# is moving up a ramp. The ramp has a kinetic friction coefficient of #2/7 # and an incline of #( 5 pi )/12 #. How far along the ramp will the box go?
- An object with a mass of #4 kg# is hanging from a spring with a constant of #2 (kg)/s^2#. If the spring is stretched by # 12 m#, what is the net force on the object?
