Question

Horkovember 21 Vertical Spring 34,056.7 A block with mass m =6.9 kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x = 0.24 m. While at this equilibrium position, the mass is then given an initial push downward at v = 5.1 m/s. The block oscillates on the spring without friction. 1) What is the spring constant of the spring? 282 N/m Submit Help 2) What is the oscillation frequency? 1.01 Hz Submit Help You currently have 5 submissions for this question.
