Mohan (mass 60 kg) runs up a flight of stairs having a rise of 5 m in 6 s. The average power supplied by him during run up is (take $$g$$​ = 10 $$\text{m/s}^2$$​):

Correct option is B

​$$\text{Given:} \\\text{Mass, } m = 60 \, \text{kg} \\\text{Height, } h = 5 \, \text{m} \\\text{Time, } t = 6 \, \text{s} \\\text{Acceleration due to gravity, } g = 10 \, \text{m/s}^2 \\\text{Work Done:} \\\text{The work done to raise the body is given by the formula:} \\W = mgh \\\text{Substitute the values:} \\W = 60 \, \text{kg} \times 10 \, \text{m/s}^2 \times 5 \, \text{m} \\W = 3000 \, \text{J} \\\text{Power:} \\\text{Power is the rate of doing work, which is given by:} \\P = \frac{W}{t} \\\text{Substitute the values:} \\P = \frac{3000 \, \text{J}}{6 \, \text{s}} \\P = 500 \, \text{W} \\\text{Convert power from watts to kilowatts:} \\P = 0.5 \, \text{kW}$$​​
