To determine the stopping distance of a car moving at 14 m/s with a coefficient of friction of 0.8, one must first create a free-body diagram (FBD) to identify the forces acting on the vehicle, including weight, friction, and normal force. The analysis focuses on the forces in the positive X direction, leading to the equation 4f=ma, where f represents the friction force. By solving for acceleration (a) and applying the kinematic equation Vf^2=Vi^2+2*a*d, with the final velocity (Vf) set to zero, the stopping distance (d) can be calculated. A tutorial is available for further guidance on this process. Understanding these principles is essential for accurately determining stopping distances in physics.
