Take gravity as 10m/sq. s
ans=(50*10*30*10)/(100*10)
=150Watt

The power of the porter is :
• Given : mass = 50 kg, Total distance traveled = 30×10 cm = 300 / 100 cm
= 3 m
Time taken = 10 sec
• Work done will be done in the form of potential energy i.e mgh
W = 50×10×3
= 1500 J
• Power = work done / time taken
= 1500 / 10
= 150 watt
• Hence power of the porter is 150 watt
