A spring elongates 0.05m when a 50N is applied to it

a) What is the spring constant of the spring

b) How long would the spring elongate if a 10kg mass is hung from the spring

c) If the energy stored in the spring of parts a) and b) is given by

E=0.5kx², how much energy is stored in the spring mass system of part b) g=10m/s²

I got a) which is k = 1000 N/m

b) i believe is 0.098m, k=m*g/k

c) is 4.802

I just want to verify if these are correct

The unit of energy is the Joule.
According to E = ½mv², a Joule (J) is equivalent to a kg⋅m²/s².
