Explanation:
Answer:
111 seconds
Explanation:
From research, it takes 4200 J to raise 1 kg of body temperature. Which means that specific heat capacity of human body with is; c = 4200 J/Kg°C
We are told that the temperature starts at 37°C and rises to 39.7°C
Thus: Δt = 39.7 - 37 = 2.7°C
Amount of energy required is given by the formula;
q = mcΔt
We are given m = 68 kg
Thus;
q = 68 × 4200 × 2.7
q = 77112 J
From research, the human body is 25% efficient.
Formula for power with velocity is;
P = F × V
F = mg = 68 × 9.81
V = 15km/h = 4.167 m/s
P = 68 × 9.81 × 4.167
P = 2779.72 W
Since the human body is 25%
Then the power of the utilized is;
25/100 × 2779.72 = 694.93 W
Now, we now that;
Power = work done/time taken
694.93 = 77112/t
t = 77112/694.93
t = 111 seconds.
Thus, it will take home 111 seconds to feel exhausted
