Question

block with mass m =6.4 kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x = 0.2 m. While at this equilibrium position, the mass is then given an initial push downward at v = 3.9 m/s. The block oscillates on the spring without friction. 1) What is the spring constant of the spring? 2) What is the oscillation frequency? 3) After t = 0.35 s what is the speed of the block? 4) What is the magnitude of the maximum acceleration of the block? 5) At t = 0.35 s what is the magnitude of the net force on the block?
