Practice Problem: Pushing Boxes

Professor Dave explains a physics problem involving moving 10 heavy boxes across a frictionless floor. The task requires understanding motion and force, specifically using Newton's second law to calculate acceleration. By applying kinematics equations, the time to move one box is determined, and then multiplied by 10 to find the total time for all boxes. The problem is simplified by assuming no friction and balanced gravitational and normal forces.
