An elevator moving up with a constant speed of
, can carry a maximum load of 1800 kg (elevator + passengers). The frictional force opposing the motion is 4000 N. Determine the minimum power (in watts) delivered by the motor to the elevator.
Text Solution
Verified by ExpertsThe correct answer is:
B
The downward force on the elevator,

The motor must supply enough power to balance this force. Hence,
