A body executing a simple harmonic motion has an angular velocity of 22 radians per second. If it has a maximum displacement of 10cm, what is its linear velocity?
1100ms-1
440 ms-1
220 ms-1
22 ms-1
2.2ms-1
Correct answer is E
Amplitude[r] =10cm =0.1m.
Angular velocity[w] =22 radians per second
Linear velocity=wr
V=22×0.1
V=2.2m/s
