Questions
A particle executes simple harmonic motion with a frequency . The frequency with which its kinetic energy oscillates is
detailed solution
Correct option is C
Kinetic energy K=12mv2=12ma2ω2cos2ω t =14mω2a2(1+cos2ω t) hence kinetic energy varies periodically with double the frequency of S.H.M. i.e. 2ω .Talk to our academic expert!
