Answer:
2.5 Watts.
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 260 Kg
Time (t) = 1 h
Height (g) = 3.5 m
Power (P) =.?
Next, we shall determine the energy. This can be obtained as follow:
Mass (m) = 260 Kg
Height (g) = 3.5 m
Acceleration due to gravity (g) = 10 m/s²
Energy (E) =?
E = mgh
E = 260 × 10 × 3.5
E = 9100 J
Finally, we shall determine the power. This can be obtained as follow:
Time (t) = 1 h = 3600 s
Energy (E) = 9100 J
Power (P) =.?
P = E/t
P = 9100 / 3600
P = 2.5 Watts
Thus, the power is 2.5 Watts.
