Solve the Problem $\frac { 5 } { \pi }$ Cycles Per Second, Determine a Trigonometric Model That Gives the Pulled

question 8

Multiple Choice

Solve the problem.
-A weight attached to a spring is pulled down 8 inches below the equilibrium position. Assuming that the frequency of the system is $\frac { 5 } { \pi }$ cycles per second, determine a trigonometric model that gives the position of the weight at time $t$ second.

• A) \(y = - 8 \cos 5 \mathrm { t }\)
• B) \(y = 8 \cos 10 \mathrm { t }\)
• C) \(y = - 8 \cos 10 t\)
• D) \(y = 8 \cos 5 t\)
