1. The problem statement, all variables and given/known data A 7.50-kg ball is placed on top of a spring with a spring constant of 475 N/m that has an initial length of 35.0 cm (h1). When the ball has reached its equilibrium position, it is supported by both springs at a height of 20.0 cm above the table (h3). If the shorter spring has an initial length of 25.0 cm, what is its spring constant? 2. Relevant equations f=-kx 3. The attempt at a solution would i find the force for h1 then use that number and 25.0 cm (0.25m) to find the spring constant? or do i have to find the force of h1 and h2, add them up, then divide that nu,ber by0.25m to find k..
