Kinetic Friction Problem Needs Help!! 1. The problem statement, all variables and given/known data A truck is traveling at constant acceleration. A box of mass 80kg rests in the bed of the truck. The Kinetic Friction between the bed and the box is 0.5. After traveling for 3 seconds the box falls off the back of the truck, what is the distance the box traveled? 2. Relevant equations F=ma F friction = Uk(Mg) Kinematic equations. 3. The attempt at a solution a=Ukg a=.5(10) a=5 D=.5(at^2) D=.5(45) D=22.5 Yet this distance, 22.5 meters, isn't even close to 4 multiple choice answers given on the test. The highest distance being 5 meters..... what am I missing here???
