The video tutorial explains a physics problem involving a rocket launched with an initial velocity of 50 meters per second and an upward acceleration of 2 meters per second squared. The rocket's engines stop at 150 meters, and the task is to calculate the velocity at engine cutoff. The instructor emphasizes the importance of drawing a diagram to visualize the problem and uses the equation V^2 = V0^2 + 2aX to find the final velocity, which is 55.7 meters per second.
