SUMMARY
The work done on the bucket in a frictionless pulley problem can be calculated using the formula for work, W = F × d, where F is the force applied and d is the distance moved. In this scenario, the mass of the bucket is 6.75 kg, and it is raised a distance of 4.00 m. The force required to lift the bucket is equal to its weight, which is calculated as F = m × g, where g is the acceleration due to gravity (9.81 m/s²). Therefore, the total work done is W = (6.75 kg × 9.81 m/s²) × 4.00 m, resulting in a definitive value of work done.
