Solve the problem.
-The position of a weight attached to a spring is $s ( t ) = - 2 \cos ( 6 \pi t )$ inches after $t$ seconds. What is the maximum height that the weight rises above the equilibrium position?
A) $6 \mathrm { in }$.
B) $\frac { 6 } { \pi } \mathrm { in }$.
C) $2 \mathrm { in }$.
D) $\frac { 1 } { 3 } \mathrm { in }$.

The maximum height above the equilibrium position corresponds to the amplitude of the cosine function, which is $2$ inches in this case.
