Thanks a lot Delphi, that's just what I needed. It seems I didn't change one of my x's to SI Units in the post above. Anyway, that last formula got me right on track. Thanks a bunch. The numbers are a little weird, but it's all I've got. The "puck" isn't the ice-hokey type, it only weighs 27...

¨I guess I'll leave the incline out of it then. With your help, I have come up with this for one of the measuremnts we took: String Extention (x) = 0.4m Distance Traveled by puck (s) = 0,205m Force on String (F) = 1N W = F*s W = 0,205 J E = (1/2)k*x^2 E = (1/2)(F/x)x^2 E = (1/2)(1/0.4)16 E...

First of all, thanks for taking the time, both of you. @G01: Yes, that makes a lot more sense... can't believe I didn't notice that. @Delphi Sorry, that was a bad explanation about the angles. It works like this. The puck is put on a plane and one edge of the plane is raised so as to...

Homework Statement The task was to find the kinetic friction of a puck that is shot from an elastic string. The puck was sliding on a cardboard plane. To do this, I was advised find the work done on the puck, and have therefore collected the following data: Distance Traveled Force the...
