1. The problem statement, all variables and given/known data A car is rolling to the right and you try to slow it down by pushing on it to the left. You are doing A) positive work B) negative work C) no work until the car comes to a stop D) You can’t tell because I didn’t tell you which way was positive. 2. Relevant equations Work = constant force * distance 3. The attempt at a solution I think its might be A because you are transferring energy to the car thus positive work but I'm not quite sure. I was tempted to pick D, but after doing a little simulation in my head I chose otherwise. Thanks!
