Well, my teacher got really upset after i showed her some of the posts from here, and still says I am incorrect. She discredits the posts here, saying how they are not credible. I really am stuck here, this seemed like an easy problem for me and all i wanted was some people to either agree or...
The problem does not state any information about if the ball penetrated a certain distance into the mud, all it says is it stopped in the mud at the bottom. No matter how i show my teacher the calculations i did to find the answer, she says its wrong, yet she doesn't have any calculations to...
Well i assumed the energy of the system was still conserved because the energy of the ball was transferred to the mud. At any second before the ball hit the mud it would have a total of 0 J energy, but after its stopped it would then only still have the -196 J from its loss in potential. That...
Homework Statement
A 2kg ball at the top of a 10m well has 0 potential and kinetic energy. The ball then falls to the bottom of the well and stops in the mud. After the ball stops what is the sum of its potential and kinetic energy?
