Solve the Problem $F = 60$ Suppose the Maximum Displacement at the Center of the It

Multiple Choice

Solve the problem.
-A guitar string is plucked so that it vibrates with a frequency of $F = 60$ . Suppose the maximum displacement at the center of the string is $s ( 0 ) = 0.53$ . Find an equation of the form $s ( t ) = a \cos b t$ to model this displacement. Round constants to 2 decimal places.

A) $\mathrm { s } ( \mathrm { t } ) = 1.06 \cos 376.99 \mathrm { t }$
B) $\mathrm { s } ( \mathrm { t } ) = 0.53 \cos 376.99 \mathrm { t }$
C) $s ( t ) = 0.53 \cos 9.55 \mathrm { t }$
D) $s ( t ) = 1.06 \cos 9.55 t$
