Asked by admin @ in Science viewed by 318 People
a man weighing 500N carried a load of 100N up a flight of stairs 4m high in 5second . what is the power?/
Answered by admin @
Total weight = 500N+100N = 600N
Height = 4m
Time = 5s
Power = work done / time taken
= (force * displacement) / time taken. ( because w = f * s)
= 600 *4/5
= 2400/5
= 480 watt
