Question

Four functions given below descirbe motion of a particle.
(I)`y=sinomega-cosomegat,(II)y=sin^(3)omegat,`
(III) `y=5cos((3pi)/(4)-3omegat),(IV)y=1+omega+omega^(2)t^(2)`
Therefore, simple harmonic motion is represented by
A. only (I)
B. (I),(II) and (III)
C. (I) and (III)
D. (I) and (II)

Answer 1

Correct Answer - B
I & III are showing S.H.M. on the basis of superpostion principle.
