Ablock with mass m =6.9 kg is hung from a vertical spring. when the mass hangs in equilibrium, the spring stretches x = 0.29 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.
1)what is the spring constant of the spring?
2)what is the oscillation frequency?
3)after t = 0.42 s what is the speed of the block?
4)what is the magnitude of the maximum acceleration of the block?
5)at t = 0.42 s what is the magnitude of the net force on the block?
