SUMMARY
The discussion focuses on calculating the force required to lift a 79 kg mass at a constant speed. The gravitational force acting on the mass is determined using the equation Fg = mg, resulting in a force of 774.2 N. To maintain constant speed, the upward force (Fp) must equal the gravitational force, leading to the conclusion that the woman must pull with a force of 774.2 N. Understanding the mechanics of the lifting process, such as the use of a rope and pulley, is essential for a complete analysis.
