Physics

Let's analyze step by step, based on the situation described:

The person lifts an object of mass vertically with uniform acceleration to a height , at which the object's speed increases to .

Work Done by the Person:

The total work done by the person on the object is the sum of the work required to lift the object to height and the work required to increase the object's speed to while it is being lifted.

1. Work done to lift the object: The force required to lift the object is equal to the gravitational force, , and the displacement is . The work done to lift the object is:
