I believe there is a force down only (force of gravity * mass) when the runner is in the air, and then after striking the ground there is an added force of kinetic friction applied in the opposite direction of the foot movement.

I've got it, but it's messy with the ratio test unless you imply some limits. Root test FTW!

Sorry, i just want to check the work. I am having some trouble convincing myself that it is correct. I keep getting that the ratio test is inconclusive (=1) so i need to see someone else work the problem.

Hey guys, was wondering if anyone could help walk me through this problem. I am fairly sure it converges by the ratio test. Thank you. http://www.wolframalpha.com/share/clip?f=d41d8cd98f00b204e9800998ecf8427e1sgqilv5iv

Is the denominator you have listed e^(x+1) or (e^x)+1? Just want to verify before trying the problem.
