When the displacement of a mass on a spring is 1/2a the half of the amplitude, what fraction of the mechanical energy is kinetic energy?
Added by Cristina M.
Step 1
Step 1: Total mechanical energy at maximum displacement is given by mechanical energy = kinetic energy + potential energy, which can be written as 0 = 1/2 * a^2 + 1/2 * k * a^2. Show more…
