1. The problem statement, all variables and given/known data Use energy to show whether or not the data agrees with the law of conservation and explain. Mass-.3105kg spring constant-6.412 Equailibrium position-1.082 Max positive postion (1) farthest distance to the right of the equlibrium position time-3.70s postion-1.303m Velocity-0.101m/s Min positive position (2) farthest distance to the left of the equilibrium postion time 4.40s postion .861m Velocity .061m/s Max Velocity (3) near the equilibrium positon time- 4.0s position-1.114m Velocity .981m/s 2. Relevant equations http://en.wikipedia.org/wiki/Simple_harmonic_motion I am in algebra based physics and haven't gone over a lot of the variables that are used in these equations. But I used the simple harmonic equations I added the kenetic to the potential in the spring. then set it equal to the potential in spring multiplied by time. Ke+Pe=Pe(t3) 3. The attempt at a solution .5mv2+.5kx2=.5kx2t3 my numbers ended up being 2.11=2.51 is this correct?
