A particle is executing simple harmonic motion along a straight line with amplitude 2 cm. When the particle is at a distance of 1 cm from its equilibrium position, its velocity is equal to 4cms-1. Then time period of oscillation is 

a
π/2
b
π2sec⁡
c
π3s
d
3 π2s

detailed solution

Correct option is D

V=ωA2−x2⇒V=ωA1−x2A2⇒V=Vm1−x2A2when x=A2, V=4Cms∴ T=2πω=2π4/3sec⁡=3.π2sec⁡
