The net force on the object is ( F = -kx ), where ( k ) is the spring constant and ( x ) is the displacement. Substituting the values, the net force is ( F = -(2 , \text{kg/s}^2) \times (5 , \text{m}) ).

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 #8 kg# is pushed along a linear path with a kinetic friction coefficient of #u_k(x)= x^2+3x #. How much work would it take to move the object over #x in [2, 6], where x is in meters?
- A truck pulls boxes up an incline plane. The truck can exert a maximum force of #2,500 N#. If the plane's incline is #(3 pi )/8 # and the coefficient of friction is #1/7 #, what is the maximum mass that can be pulled up at one time?
- An object with a mass of #6 kg# is pushed along a linear path with a kinetic friction coefficient of #u_k(x)= 2+sinx #. How much work would it take to move the object over #x in [2, 5], where x is in meters?
- How fast will an object with a mass of #4 kg# accelerate if a force of #34 N# is constantly applied to it?
- An object with a mass of #7 kg# is hanging from a spring with a constant of #3 (kg)/s^2#. If the spring is stretched by # 2 m#, what is the net force on the object?
