come on people, surely this is an easy question to answer. Can I rephrase it in a better way?

I don't think I am wording myself clearly. If the baby and the mattress were attached to each other, and you pulled the baby upwards by 16 cm and then released it, then the spring force on the baby would result in a downwards acceleration greater than g. The baby and the spring aren't...

and at a displacement of about 16cm... the spring force and baby are in equilibrium

Yes, would this be correct?

For part b), Is this actually pretty easy? Can you just find the spring displacement that would result in an initial acceleration of -9.8m/s^2 if freely released? So the baby would be accelerating downwards at a lesser rate than the cot spring... leaving the spring?

Hello physicsforum people, I'm not sure how many significant figures I should express a confidence interval to. I have confidence intervals for means that I need to express in a lab report, which I am going to do in the something ± something fashion. (I have assumed a normal distribution of...
