A mass of 0.73 kilogram, attached to a spring with a spring constant of 43 N/m, is set into simple harmonic motion. Find the magnitude of the acceleration of the mass when at its maximum displacement of 0.39 meter from the equilibrium position?
They should have opposite magnitudes. They should have equal magnitudes. Their x-components should be equal. They must be parallel (point in the same direction). They should be anti-parallel (point in opposite directions). Their y-components should b..
