• In one second the power generated is:

  w = mgh = 1.2×10^6 x 9.8 x50= 588 x 10^6 (J)

• Power = Energy transferred / Time taken

  Energy Transferred in one second ( Power) = mgh/s

  = (1.2×10^6)(9.8)(50) = 588000000 J/s

  Power = 588000000 W

• Power is work done / time

  Work done in one second =[ rate of fall of mass]gh =

  1.2* *9.81*50 x 10^6 J/s = 5.886e+8 W
