Ablock with mass m= 6.7 is hung from a vertical spring. when the mass hangs in equilibrium, the spring stretches x = 0.29m. while at the equilibrium position, the mass is then given an initial push it downword and v 4.6 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?
