Question

I T A 5-kg block is hung on a vertical spring with a spring constant k 100 N/m and then slowly released and left at rest in its new equilibrium position. 1. How much does the spring stretch until it finds its new equilibrium position? 2. If this load is pushed by hand up 2 cm and then suddenly dropped allowing it to oscillate about its equilibrium, what is the angular frequency of its oscillation? 3. What function of time is the vertical displacement of the load given the initial conditions in described above in 2. 4. What function of time is the velocity of the load given the initial conditions in 2. 5. What function of time is the acceleration of the load given the initial conditions in 2. 6. What is the maximum elastic potential energy of the load? 7. What is the kinetic energy of the load at the 5th second of the oscillation ?
