An elevator can carry a maximum load of \(1800~\text{kg}\) (elevator + passengers), moving up with a constant speed of \(2~\text{m/s}.\) The frictional force opposing the motion is \(4000~\text{N}.\) The minimum power delivered by the motor to the elevator is:
1. \(59000~\text{W}\) 
2. \(44000~\text{W}\) 
3. \(11000~\text{W}\) 
4. \(22000~\text{W}\)
