A(n) 96.1 g ball is dropped from a height of59.1 cm above a spring of negligible mass.The ball compresses the spring to a maximum displacement of 4.75403 cm.The acceleration of gravity is 9.8m/s^2.
Calculate the spring force constant k.
Answer in units of N/m

kx²/2=mgh
k=2mgh/ x²=
2•0.0961•9.8•0.591/(0.04754)²=...(N/m)
