A spring is linear if it obeys Hooke's Law, which indicates that the applied force to stretch the spring is

. For a linear spring,

is constant. If, instead,

is not constant, then the spring is called nonlinear. Furthermore, if

increases as

increases, then the spring is said to be progressive, and if

decreases as

increases, then the spring is said to be degressive. Let

be the applied force function for a spring (with

in N and

in cm ). Indicate whether the spring is progressive or degressive. Select the true statement about the spring. The spring is progressive. The spring is degressive. Compute the work required to stretch the spring from 6 to 10 cm . (Use decimal notation. Give your answer to two decimal places.)
