A block of mass m = 10.0kg is attached to the end of an ideal spring. Due to the weight of the block, the block remains at rest when the spring is stretched a distance h= 8.00cm from its equilibrium length. (Figure 1) The spring has an unknown spring constant k. Take the acceleration due to gravity to be g = 9.81m/s2 .

What is the spring constant k?

Express your answer in newtons per meter.

k =

  N/m  

Part B

Suppose that the block gets bumped and undergoes a small vertical displacement. Find the resulting angular frequency ? of the block's oscillations about its equilibrium position.

Express your answer in radians per second.

? =

  radians/s
