A spring has a length of 0.333 m when a 0.300 kg mass hangs from it, and a length of 0.750 m when a 2.42 kg mass hangs from it. (Use 9.80 m/s2 for g.)

(a) What is the spring constant of the spring? (Give your answer to at least two decimal places.) in N/m

(b) What is the unloaded length of the spring? in meters

Please provide step by step explanations, thank you!

I've gotten around 56N/m and 31N/m for (a) and both are wrong.

An ideal spring hangs from the ceiling. A 2.15 kg mass is hung from the spring, stretching the spring a distance d = 0.0905 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L = 0.0225 m from the equilibrium position and released. What is the kinetic energy of the mass at the instant it passes back through the equilibrium position?
