In a simple harmonic oscillation, what fraction of total mechanical energy is in the form of kinetic energy, when the particle is midway between mean and extreme position.

Step-by-step solution

K = 1 2   m ω 2   A 2 - x 2 = 1 2   m ω 2   A 2 - A 2 4 = 1 2   m ω 2 3   A 2 4 K = 3 4 1 2   m ω 2   A 2
