text: how do i find angular velocity? it's telling em to actully find the maximum acceleration. i found that maximum acceleration is amplitude x omega squared. so i was wondering how i can find the omega. they gave me that the frequency is 2.0 x 10 to the 12th hertz and that the amplitude is 1.1 x 10 to the negative 11th meters. i thought that i could find it by using the inverse of 2 x 10^12. the angular velocity is given by  w = 2*pi*frequency. in your case  w = 2*pi*2*10^12 = 1.257 * 10^13 rad/s hence the max acceleration = 1.1*10^-11*(1.257*10^13)^2 = 1.738*10^15 m/s
