(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 2 kg object attached to a spring moves without friction and is driven by an external force given by F = (3.00N)sin(2[tex]\pi[/tex]t). The force constant of the spring is 20.0N/m.

Find the amplitude of the motion.

2. Relevant equations

I am not sure but I am trying to use:

A = (F_{0}/m)/[tex]\sqrt{}(w^2-w_{0}^2)^2[/tex]

3. The attempt at a solution

Applying this equation using w equals 2pi and w_{0}is k/m (10) gives an amplitude of 0.00173. The solution in the book says 5.09cm.

Am I approaching this question correctly?
