A spring scale has 0.08m length when no force is applied to it. When a 2 N pull is applied to the spring, it stretches to 0.12m. Apply Hook's Law to find the spring constant k in [N/m]. Using this spring constant, determine the natural frequency of oscillation of the spring scale for a mass of M=0.5 kg. Round off your result to one digit after the decimal point. Write all steps of your solution, starting from the equations
