Please do excuse if certain terms are not the most technical ones as I am translating the problem from another language. Do feel free to kindly inform me of the more technical term that substitues the sloppy one I've used. (And do excuse the generally bad English overall :-))
1. Homework Statement
A certain body of mass with the beginning kinetic energy of 48 J is moving along a horizontal surface and then stopping due to the effect of the friction force of onstant 6 N.
Calculate the path along which the body was stopping (in meteres).
Ek = m x v^2 / 2
Wk = Ek
Ffr = G x mi
Ffr = Wfr / d
I was working through the formulas and managed (I think) to extract the mass from both Ek and Ffr and got m = 96 J / v^2 and m = 0,6 kg & mi. However, I don't think this will be of any help, and conceptually I feel I should be looking somewhere else - unfortunately my imagination isn't working well at the moment.
What should I do?
Also, I was thinking perhaps if Wk is F times d, then I can somehow use that as well, although I feel this might reflect my faulty understanding of this formula.
Please help!
