question 286

Multiple Choice

Solve the problem.
-A guitar string is plucked so that it vibrates with a frequency of $\mathrm { F } = 67$ . Suppose the maximum displacement at the center of the string is $s ( 0 ) = 0.51$ . Find an equation of the form $s ( t ) = a$ cos bt to model this displacement. Round constants to 2 decimal places.

• A) \(s ( t ) = 0.51 \cos 420.97 \mathrm { t }\)
• B) \(s ( t ) = 0.51 \cos 10.66 t\)
• C) \(s ( t ) = 1.02 \cos 420.97 \mathrm { t }\)
• D) \(s ( t ) = 1.02 \cos 10.66 \mathrm { t }\)
