eginarrayl	extWe know that,\ 	extspeed in S.H.M,\ v=omegasqrta^2-x^2\ v_max=aomega\ 	extGiven in question,\ v=fracv_max2=omegasqrta^2-x^2\ Rightarrowfracaomega2=omegasqrta^2-x^2\ Rightarrow x^2=a^2-fraca^24\ Rightarrow x=fracsqrt32a\ 	extAt, x=fracsqrt32a, 	extspeed is half of its maximum. endarray
