dear hemat , here is the solution


angular frequency = 2pi(f)  or directly proportional to f ...


f is the frequency of motion ...


x = Asinwt       ...........1


angular frequency of motion is w ...


KE = mW2A2sin2wt/2


    = (mW2A2/2)[(1-cos2wt)/2]                       (  sin2@ = (1-cos2@)/2  )


angular frequency of KE = 2w


  angular frequency is twice so frequency will be twice..


f1 = 2f


approve my ans if u like
