A block with a mass of 0.30 kg is attached to a horizontal spring. The block is pulled back from its equilibrium position until the spring exerts a force of 1.2 N on the block. When the block is released, it oscillates with a frequency of 1.1 Hz. How far was the block pulled back before being released?

The value is  

Explanation:

From the question we are told that

   The mass of the block is  

   The force exerted is  

   The  frequency is  

Generally the spring constant of the spring is mathematically represented as

=>    

=>    

Generally the spring constant is also mathematically represented as

=>  

=>  

lol

explanation:

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
