Which of the following functions represent SHM : sin^(2)omegat |
|
Answer» Solution :A MOTION will be SHM if acceleration is directely proportional to its displacement `a=- OMEGA^(2)y` `y= sin^(2) omega t` `rArr (dy)/(dt)=2(sin omega t)(omega COS omega t)` `= omega sin 2 omega1`, `(d^(2)y)/(dt^(2))=-2 omega^(2)cos 2omega t, rArr (d^(2)y)/(dt^(2)) prop y` `:.` It is oscillatory but not SHM. |
