A mass hangs from a spring. Find the spring constant and frequency of oscillation. In the figure, the LEFT drawing shows the spring's NATUAL length. In the RIGHT drawing a block of mass m= 10.0 kg is attached to the end of the spring. Due to the weight of the block, the block remains at rest when the spring is stretched a distance h= 9.00 cm from its Natural length. This is the EQUILIBRIUM position of the block where the NET force is zero -- the spring force and the block's weight balance each other. The figure shows a spring in two states: with a block of mass m attached and without it. The block stretches the spring a distance h from its equilibrium length. The y-axis is directed vertically upwards.The spring has an unknown spring constant k. Take the acceleration due to gravity to be g = 9.81 m/s2 . Part A What is the spring constant k?
