Ok, a simple question...
Are we to assume that the acceleration from 0 to 60 mph is constant, and that the acceleration from 60 mph to 100 mph is constant (but different)?
Anyway, you can solve this problem with one formula:

Performance map of a cluster detection test using extended power
Conventional power studies possess limited ability to assess the performance of cluster detection tests. In particular, they cannot evaluate the accuracy of the cluster location, which is essential
in such assessments. Furthermore, they usually estimate p... | {"url":"http://www.ij-healthgeographics.com/content/12/1/47","timestamp":"2014-04-17T21:23:39Z","content_type":null,"content_length":"127166","record_id":"<urn:uuid:6c7a9c62-c5a5-415a-8446-d30d33d88af3>","cc-path":"CC-MAIN-2014-15/segments/1397609532128.44/warc/CC-MAIN-20140416005212-00305-ip-10-147-4-33.ec2.internal.w... |

The 1999 Nobel Prize in Physics
Porter Johnson; 12 October 1999

Difficult variable to solve for. includes hyperbolic cos.
I have the equation y = 1/k * ln(cosh(SQRT(g*k)*t))
My goal is to solve for k. This is for aerospace engineering and "k" includes a variable that I need.
