Work Energy Theorem Example Problem

The video tutorial covers a physics problem involving a 5.0 kg mass and its change in velocity. The teacher guides students through solving the problem using the work-energy theorem, explaining why other work equations are not applicable. The process includes calculating the net work done on the mass by considering the change in kinetic energy. The tutorial emphasizes the importance of understanding vector operations and careful handling of negative values in calculations.
