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.
v = -w Asin(ωt+Φ) = -wx
Conservation of Energy:
1/2kx2 + 1/2mv2 = 1/2kA2
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?
