What is the average power developed by a motor as it lifts a 400.-kilogram mass at constant speed through a vertical distance of 10.0 meters in 8.0 seconds

The average power developed by a motor is 4905 Watts.

Explanation:

The average power is given by:

Where:

W: is the work

t: is the time = 8.0 s

First, let's find the work:

Where:

F: is the force

d: is the displacement = 10.0 m

The force is in the vertical motion, and since the movement of the mass is at constant speed the force is:

Hence, the average power is:

Therefore, the average power developed by a motor is 4905 Watts.
