SUMMARY
The discussion focuses on calculating the distance moved by an object when a 25lb force is applied at an angle of 60 degrees, resulting in 125ft-lb of work done. The relevant equation for work is defined as the product of force, distance, and the cosine of the angle between the force and the direction of motion. Using the formula W = F * d * cos(θ), the distance can be calculated as d = W / (F * cos(θ)). Substituting the values, the distance moved is determined to be 10 feet.
