Below are sets of values for the spring constant k, damping constant b, and mass m for a particle in damped harmonic motion. which of the sets takes the longest time for its mechanical energy to decrease to one-fourth of its initial value? k = k_0, b = b_0, and m = m_0 k = 3k_0, b = 2b_0, and m = m_0 k = k_0/2, b = 6b_0, and m = 2m_0 k = 4k_0, b = b_0, and m = 2 m_0 k = k_0, b = b_0, and m = 10m_0
