A 4.0 kg-block attached to a 20 N/m-spring constant spring moves on a frictionless horizontal surface, its position-versus-time graph is shown below. At t = 4.0 s, what is the magnitude of the acceleration of the block, in m/s2? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
