Question

What is the power of the person
having 80 gram mass if he
climbs a 50 m tall hill in of
10 minutes?​

Answer 1

Answer:

If a man of mass 80 g climbs a hill of height 50 m in 10 minutes or 600 seconds.

However, its potential energy,

defined by U=m×g×h

Since its mass is 80 g

g is somewhere between 9,78 N/kg and 9,83 N/kg, at the equator, where the radius is the farthest from the center of the earth and the poles, where is the nearest, but we will take 9,81 and;

h is 50m

U = 80*9.81*50

= 39,240

However, as you might guess too, the energy spent is P=W/t so,

P = 39240/600

P = 65.4 watt
