When a spring is pulled with a force of 5xx10^(5) dyn, it elongates by 0.1 m. What mass should be attached to the end of the spring so that when pulled a little downwards and released, the mass can perform 2 complete oscillations per second? What will be the maximum velocity of the mass when the amplitude of vibration is 0.01 m?

1.	When a spring is pulled with a force of 5xx10^(5) dyn, it elongates by 0.1 m. What mass should be attached to the end of the spring so that when pulled a little downwards and released, the mass can perform 2 complete oscillations per second? What will be the maximum velocity of the mass when the amplitude of vibration is 0.01 m?
