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

Answer»

strong>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
