A block with mass m =7.5 kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x = 0.25 m. While at this equilibrium position, the mass is then given an initial push downward at v = 4.1 m/s. The block oscillates on the spring without friction.
Spring constant is 306N/m. Oscillation frequency is 1 Hz. After t = 0.3 s, v = 1.232 m/s, a = 26.2m/s^2.
At t = 0.3 s what is the magnitude of the net force on the block?
