In Concept Simulation 10.3 you can explore the concepts that are important in this problem. A block of mass m = 0.838 kg is fastened to an unstrained horizontal spring whose spring constant is k = 97.5 N/m. The block is given a displacement of +0.158 m, where the + sign indicates that the displacement is along the +x axis, and then released from rest. (a) What is the force (with sign) that the spring exerts on the block just before the block is released? (b) Find the angular frequency w of the resulting oscillatory motion. (c) What is the maximum speed of the block? (d) Determine the magnitude of the maximum acceleration of the block
