Please help me out, I'm new here, and I only have one more attempt on this problem, totally lost. 1. The problem statement, all variables and given/known data A(n) 142 g ball is dropped from a height of 62.2 cm above a spring of negligible mass. The ball compresses the spring to a maximum displacement of 4.35501 cm. The acceleration of gravity is 9.8 m/s^2 . Calculate the spring force constant k. Answer in units of N/m. 2. Relevant equations F=-kx 3. The attempt at a solution mgh=-kx (.142)(9.8)(.622)=-k(0.435501) k=19.875 ???
