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
