With mass 2500 kg, the elevator has weight
(2500 kg) <em>g</em> = (2500 kg) (9.80 m/s²) = 24,500 N
The net force on the elevator is 30,000 N - 24,500 N = 5500 N (because its weight pulls it downward, while the tension pulls upward).
The acceleration <em>a</em> of the elevator is obtained from Newton's second law,
(2500 kg) <em>a</em> = 5500 N
<em>a</em> = (5500 N) / (2500 kg)
<em>a</em> = 2.2 m/s²
If the speed is constant, the acceleration a must be zero. Since force F = m•a, the total force must be zero.
In a 1D case, work W is the product of force F and distance d: W = F • d.
Since there is no more information given about friction or air resistance, I have to assume you are looking for the work done by the total force, wich is also zero.
