The discussion centers on calculating the negative acceleration of a vehicle during a skid, given a total stopping distance of 50 meters, a driver reaction time of 1 second, and a coefficient of sliding friction of 0.58. The initial velocity is approximated at 36.66 m/s, derived from the equation D = V² / (2μg). Participants emphasize the importance of separating the problem into thinking distance and braking distance to accurately determine the negative acceleration.
PREREQUISITESThis discussion is beneficial for physics students, automotive engineers, and safety analysts focused on vehicle dynamics and stopping distance calculations.

Total Stopping distance = 50 meters
Driver Reaction Time = 1 Seconds
Coefficient of sliding friction = 0.58
Homework Equations
D=(Total Distance)=V^2/2μg
The Attempt at a Solution
v≈36.66 (Initial Velocity) but I am sure what do after this step to find the negative acceleration, it would help if you just provide the formula to use.[/B]
