For a particle executing simple harmonic motion,  the kinetic energy K is given by, K0cos2ωt.The maximum value of PE is 

a
K0
b
2K0
c
3K0
d
4K0

detailed solution

Correct option is A

The mechanical energy of a simple harmonic motion is conserved. Since K=K0  cos2⁡ωt, the maximum value of Kinetic energy = K0 = maximum value of potential  energy at the extreme position of the body in simple harmonic motion.
