A spring-block system executes simple harmonic motion. The mass of the block is m = 12 kg and the total energy is E = 18 J. The amplitude is A = 0:10 m. (a) Find the spring constant. (b) Find the maximum speed and the maximum acceleration. (c) What is the total distance traveled by the block over one complete period? (d) What is the total displacement of the block over one complete period? Please explain how you solved the problem; not just list the answers
