## Homework Statement

A 171 g object on a spring oscillates left to right on a frictionless surface with a frequency of 3.00 Hz and an amplitude of 11.0 cm.

(a) What is the spring constant?

N/m

(b) If the object starts from rest at x = 11.0 cm at t = 0 and the equilibrium point is at x = 0, what equation describes its position (in centimeters) as a function of time (in seconds)?

x(t) =

## Homework Equations

(a) was solved and the spring constant was found to be 60.75 N/m

(b) b) x = A cos (omega t)

## The Attempt at a Solution

omega is 2pi*3 hZ so omega would be 6pi. Thusly, x(t) = .11 cos (6pi) t

Am I correct? Our online homework system is not accepting my answer and I am not certain if it is because I made a mistake in physics or the syntax of my answer. Could someone verify I am right or wrong?
