Questions
Identify the correct statements for an SHM
(i) Displacement leads velocity by
(ii) Displacement lags velocity by
(iii) Acceleration leads velocity by
(iv) Acceleration lags velocity by
detailed solution
Correct option is B
InSHM, displacement y=Asin wt differentiate with respect to time t Velocity,v= Awcoswt=A wsin (ωt+π2), differentiate with respect to time t again and acceleration,a=–Aw2sin wt=Aw2sin(wt+π ) Velocity leads displacement by 0.5 π, acceleration leads velocity by 0.5 π.Talk to our academic expert!
