if my car is stuck in a hole.... I'm just doing a taught experiment, and i want to be able to prove or not that pushing down on a car that is stuck in a hole(increasing down force) uses less work force than pushing it from the back. edit: what i came up with is- ASSUME my car is 10kg and it takes 100N to get out of the hole, but it is only exerting 60N. so a=6m/s^2 and it is required an extra 4m/s^2 to get out. down force is 9.81*10=98.1N how much more do i need to get out of the hole?
