    Forces on a car skidding to a halt.

    That's what I thought originally, but it's evidently incorrect Thanks, but one must take into consideration that the car is decelerating, not standing still, so this becomes more complicated. Your solution (as was mine) is for a stationary car. The decelerating car would have a tendendency...

    Normal Force, Friction Force, Accel problem

    I'm having difficulty with the identical problem, which I describe in more detail under the thread "Forces on a car skidding to a halt," which reads as follows: A car on a horizontal road makes an emergency stop such that all four wheels lock and skid. The coefficient of friction between tires...

    Forces on a car skidding to a halt.

    Homework Statement The following is an instructive problem which I've been unable to solve. A car on a horizontal road makes an emergency stop such that all four wheels lock and skid. The coefficient of friction between tires and road is mu=0.40. The distance between the front and rear...
