The box was released on a flat wooden surface. The problem is: Create a equation that will solve for distance that the box travels after losing contact w/ the rubber band. Variables available for use:delta D, g, delta X , m(mass), K and Mew No other information was given. Thank you. Last edited by spade94; May 11th 2009 at 05:06 PM.

Equate both and get u^2. Now, this K.E. is used up in doing work against the force of friction F = - MU x mg. Let the box stop after a distance = s . So work W = F.s. Now equate every thing and work it out.
