1. The problem statement, all variables and given/known data Car: mass = 200g Moving at 30 m/s Braking force of 10000N. How far does the car travel before stopping? 2. Relevant equations W=m x N w = F (delta x) 3. The attempt at a solution I found work, (2000)(10000) = 20,000,000 Then rearranged the second equation to get delta x, and got 2000 as my answer. The answer is 90m and I'm not getting it. Any suggestions?
