P = w/t
Unit of power = unit of work/ unit of time = j/s = js raise to power –1 = watt or simply W
1kW is thousand times of 1W. 1kW = 1000W
1kW h is the bigger unit for work used mostly for machines. 1kW h = 3.6 * 10 raise to power 6 J
In the Ques, height = 20m, mass = 25 metric tonne = 25000 Kg, Acceleration = 10ms raise to power –2
Work = mgh = 25000*10*20 = 50,00,000 J = 5000 Kj
Power can't be found due to nothing given about time taken.
