Answer:

B

Explanation:

B is the mean position.At the mean position, the velocity of the particle in S.H.M. is maximum and displacement is minimum, that is, x=0. Therefore, K.E. = 1/2 k ( a² – x²) = 1/2 k ( a² – o²) = 1/2 ka². Thus, the maximum kinetic energy is expressed by K.E = ½ ka²

Answer:

Point B is the location of the greatest kinetic energy. This is the point where the pendulum is moving with the greatest velocity.
