Consider a mass-spring system. The spring has a spring constant of 1.18e+3 N/m. At the end of the spring there is a mass of 4.05 kg. At the moment that the block is at the system's equilibrium position, it has velocity 2.90 m/s. What will be the maximum displacement of the block from equilibrium if we ignore all friction.

(III) A block of mass m is attached to the end of a spring (spring stiffness constant k), Fig. 6-43. The mass is given an initial displacement $x_0$ from equilibrium, and an initial speed $v_0$ .Ignoring friction and the mass of the spring, use energy methods to find ($a$) its maximum speed, and ($b$) its maximum stretch from equilibrium, in terms of the given quantities.

(II) A block of mass $m$ is attached to the end of a spring (spring stiffness constant $k ),$ Fig. $6-40$ . The block is given an initial displacement $x_{0}$ , after which it oscillates back and forth. Write a formula for the total mechanical energy (ignore friction and the mass of the spring) in terms of $x_{0}$ , position $x$ , and speed $v$ .
