1. The problem statement, all variables and given/known data A 105.0 N grocery cart is pushed 11.0 m along an aisle by a shopper who exerts a constant horizontal force of 40.0 N. If all frictional forces are neglected and the cart starts from rest, what is the grocery cart's final speed? 2. Relevant equations Wnet=deltaKE 3. The attempt at a solution So i used that equation which ended up to mad=1/2mv2 (10.7)(9.81)(11)=1/2(10.7)(v2) v= 14.7 m/s But it ended up being wrong, i don't get it. and also i could cancel out the masses right? but it would still give me same answer so it wouldn't matter. Thanks for your help!
