Question

An elevator is designed to lift a load pf 1000kg through 5 floor pf a building at 4 m per floor in 5s . What is the power of the elevator

Answer 1

Answer:

Power = 8000 watt

Explanation:

Power = force × velocity

force = 1000 kg × 10 m/s2 ( value of g ) = 10000 Newton

velocity = 4/5 m/s

so , power = 10000× 4/5 = 8000 watt
