1. The problem statement, all variables and given/known data attached 2. Relevant equations equation in the problem k = 898 N/m m = 90.7g = .0907kg d = 27 inch = .6558m g = 9.8 m/s 3. The attempt at a solution h = [(898n/m)/(2)(.0907kg)(9.8m/s)](.6558m)^2 - (.6558) that is for the H. when computing this is got 217.55m. I am assuming the way the equation is written out for h in the problem that is how to set it up. now it asks for velocity. when it gets back to zero. We will say E1 = E2.... at E1 it is all potential energy and no kinetic. and at E2 where we find final velocity it is all kenetic and no potential? so then we have mgh = 1/2 mv^2...... plus the top equation in for h then isolate V and solve. thanks for any help.
