hmmm i see. i was just trying to show if pushing from the back is less or more efficient than increasing downforce. i guess it depends.

so what are you saying, applying force to the part that's in the hole is eaiser than pushing from the back? that's what i am trying to show mathematically. EDIT: i was assuming the car can only exert 60N and it needs 100N to get out, so an additional 40N of force from the back or increasing the...

okay let's simplify the question. the car can only exert 60N so let's say we need 40N to move it. (10kg) coefficient of friction is F/W = 40/98.1= .40775

down force increases friction... according to my regents physics essentials textbook. oh i see we need 100n for the friction to be enough to take it out. so what i am saying is that we need 40n pushing from the back, how much do we need to increase down force to take it out? Down Force=...

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...
