1. The problem statement, all variables and given/known data How much work must be done by frictional forces in slowing a 1000kg car from 24.9 n/s to rest 2. Relevant equations 3. The attempt at a solution I just never fully understood how slowing down worked. I just need a nudge in the right direction not you guys doing the work for me. I don't think I'm supposed to do a force analysis, but then again I don't know how to do the problem.
