Okay so this is a "law of conservation of energy" type of question. it's simple but i was absent for a week and im completely lost so i need an explanation.

we rolled a golfball down a ramp (once at 0.3 m and 0.45 m).
the initial potential energy was 0.135 joules (at 0.3 m)
and the other initial potential energy was 0.203 joules (0.45 m)

if u need the median times:
0.45 m = 0.91 s
0.3 m = 1.42 s

so my question is.. does the experiment demonstrate law of conservation? why or why not
and finally if it does.. how? ?

Industrial processes often require the damping of vibrations. consider a workbench that uses four large ideal springs in place of traditional legs, with each spring supporting one corner of the workbench and exhibiting a force constant of 47500 n/m. this workbench is used when creating products that involve highly unstable chemicals. according to specifications, the acceleration of the manufacturing equipment must be held to less than 22.3 m/s2 for the manufacturing process to proceed safely. the amplitude of vibrations are expected to remain under 0.622 mm throughout. given that the workbench and maufacturing equipment combine to 6.05 kg, find the maximum acceleration expected of the equipment and workbench. (ignore the mass of the springs.)
