Answer:
Correct answer: P = 38,793.1 W = 38.7 kW
Explanation:
Power is calculated according to the following formula:
P = A / t
where A is the work performed and t the elapsed time
work is a measure of changing energy
A = ΔEp = m · g · h we will take that g = 10 m/s
A = 4,500 · 10 · 25 = 1,125,000 J
P = 1,125,000 / 29 = 38,793.1 W = 38.7 kW
P = 38,793.1 W = 38.7 kW
