A small electric motor is used to lift a
0.50kilogram mass at constant speed. If the
mass is lifted a vertical distance of 1.5 meters in
5.0 seconds, the average power developed by the
motor is

Damon,
change in potential energy = m g h
energy/time = power = m g h /t
= .50 * 9.81 * 1.5 / 5
Joules/second or Watts

Yangtze,
calculate the power out in watts and horse power of an 80 kg man that climbs a flight of stairs 5.8m high in 4.0s.
