Constant Acceleration Problem Solving Techniques

The video tutorial explains how to solve a physics problem involving a car stopping with constant acceleration. It covers the use of the distance formula, solving for time using velocity and acceleration, and calculating the displacement. The tutorial concludes with the final calculation of the stopping distance.
