because if you multiply 3 by 0 its the same thing as saying 0+0+0 and that is still 0 (hope this was helpful)
The power of the man is 233.33 W
We'll begin by calculating the energy used by the man. This can be obtained as follow:
Mass (m) = 35 Kg
Height (h) = 0.50 m
Acceleration due to gravity (g) = 10 m/s²
<h3>Energy (E) =? </h3>
<h3>E = mgh </h3>
E = 35 × 10 × 0.5
<h3>E = 175 J</h3>
Thus the man used 175 J of energy.
Finally, we shall determine the power. This can be obtained as follow:
Energy (E) = 175 J
Time (t) = 0.75 s
<h3>Power (P) =? </h3>
<h3>Power = Energy / time </h3>
Power = 175 / 0.75
<h3>Power = 233.33 W </h3>
Therefore, the power of the man is 233.33 W
