## Homework Statement

A cheerleader waves her pom-pom in SHM with an amplitude of 17.3 cm and a frequency of 0.830 Hz .

Find the maximum magnitude of the velocity.

## Homework Equations

v = -w Asin(ωt+Φ) = -wx

or

Conservation of Energy:

1/2kx

^{2}+ 1/2mv

^{2}= 1/2kA

^{2}

## The Attempt at a Solution

I tried v = -ω(x) using 0.173 as x

v = -5.21(0.173) = -0.0901 > wrong

I got the ω by solving for period T (1.205s), i then made this equal to 2π/ω to solve for omega.

I have yet to try the conservation of energy. But what would be the x in this case?
