Solve the Problem $\frac { 1 } { 5 }$ Second, Determine a Trigonometric Model That Gives the Position of Pulled

question 75

Multiple Choice

Solve the problem.
-A weight attached to a spring is pulled down 3 inches below the equilibrium position. Assuming that the period of the system is $\frac { 1 } { 5 }$ second, determine a trigonometric model that gives the position of the weight at time $t$ seconds.

• A) \(\mathrm { s } ( \mathrm { t } ) = 3 \cos \frac { 1 } { 5 } \mathrm { t }\)
• B) \(s ( t ) = 3 \cos 10 \pi t\)
• C) \(s ( t ) = - 3 \cos 5 \pi t\)
• D) \(s ( t ) = - 3 \cos 10 \pi t\)
