5. A 9-lb weight, suspended from a spring having spring constant k = 32 lb/ft, is perturbed from its equilibrium state with a certain upward initial velocity. The amplitude of the resulting vibrations is observed to be 4 in. (a) What is the initial velocity? (b) What are the period and frequency of the vibrations?

Spring Motion The position of a weight attached to a spring is $s(t)=-4 \cos 10 t$ inches after $t$ scconds. (a) Find the maximum height that the weight rises above the equilibrium position of $s(t)=0$ (b) What are the frequency and period? (c) When does the weight first reach its maximum height? (d) Calculate and interpret $s(1.466)$

4. A 4.5-kg mass is attached to a spring with a spring constant of k = 20 N/m. The mass is set in motion from the equilibrium position with an initial velocity of 10 m/s. (a) Write an IVP to represent the spring-mass system. (b) Solve for z(t) and identify the natural frequency.
