If the displacement of a particle executing SHM, is given by y=0.30 sin (220t+0.64) in metre, then the frequency and the maximum velocity of the particle are (t is in seconds)…………….

If the displacement of a particle executing SHM, is given by y=0.30 si

1.	If the displacement of a particle executing SHM, is given by y=0.30 sin (220t+0.64) in metre, then the frequency and the maximum velocity of the particle are (t is in seconds)…………….
Answer» 35 Hz, 66 m/s 45 Hz, 66 m/s 58 Hz, 113 m/s 35 Hz, 132 m/s Solution :FREQUENCY `F=(omega)/(2pi)=(220)/(6.28)=35Hz` Maximum particle VELOCITY `v_(max)=Aomega=0.30xx220=66m//s`
