... 16. [A] This is a conservation of energy problem, setting it up, we get: mgh+0.5mv²=0.5kx², because there is both potential and kinetic energy initially, then it is all elastic potential at the end. Solving for x, we get: x=√[(mgh+0.5mv²)/(0.5k)]=√[((5)(9.8)(2)+(0.5)(5)(10)²)/((0.5)(1000))]=0.834 m ...
