Explanation:
Variables:
Power is measured in Watts. A Watt is equivalent to energy over time.
Initial Energy:
Final Energy:
Power over the interval:
Since the acceleration is uniform, we can assume that the power was increasing uniformly during this period. So each second, the power increased by:
So at
