Question

If a man of mass 70kg climbs up a mountain of height 30m in 5minutes .what is his power​

Answer 1

Answer:

70 W

Explanation:

Mass = 70 kg

Distance = Height = 30 m

Time = 5 min = 300 s

g = 9.8 m/s² OR 10 m/s²

P = E/t                ( Energy/Time )

  = mgh/t         ( Potential Energy )

P = (70 * 10 * 30) / 300     ( I chossed  10 m/s² for easier calculation )

  = 70 W
