A block with mass m =6.5 kilogram is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x = 0.23 meters. While at this equilibrium position, the mass is then given an initial push downward at v = 4.2 meter per second. The block oscillates on the spring without friction.
1) Evaluate what is the spring constant of the spring?
2) Evaluate what is the oscillation frequency?
3) After t = 0.39 second compute what is the speed of the block?
4) Evaluate the magnitude of maximum acceleration of the block?
5) At t = 0.39 second, evaluate the magnitude of the net force on block?
