Work is the same as energy. With the use of energy formula, the work done is 4 J
The work done on an object can be defined as the product of force and distance in the direction of the force. It is synonymous to energy and it is measured in Joule.
Given that a person lifting a 2.0-kg object from the bottom of a well at a constant speed of 2.0 m/s for 5.0 s.
The given parameters are
Work = Energy = 1/2mv²
W = 1/2 × 2 × 2²
W = 0.5 × 2 × 4
W = 4 Joules
Therefore, the much work that is done by the person is 4 Joules.
