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

A

35 Hz, 66 m/s

B

45 Hz, 66 m/s

C

58 Hz, 113 m/s

D

35 Hz, 132 m/s

Text Solution

Verified by Experts

The correct Answer is:
A
`x=0.30sin(220t+0.64)m`
`omega=220`
`2pin=220`
`n=(220)/(2xx(22)/(7))=(10xx7)/(2)=35Hz`
`v_(m)=Aomega`
`=0.30xx220=66m//s`
