1. The problem statement, all variables and given/known data A car with a flat front is accelerating in the horizontal direction so that an 80 kg person on the front face of the car stays in equilibrium. The coefficient of friction between the person and the surface of the car is .8. The resistance force by the air on the person is Fair=320 N. The minimum acceleration of the car should be: (A) 25 (B) 16.5 (C) 12.5 (D) 8.5 (E) 4 2. Relevant equations Ff=μFN 3. The attempt at a solution I know a free body diagram would help for this one, but I'm confused as to the directions of the air and normal force.
