Answer:
0.057 joules is needed to create the total rotational energy each second.
Explanation:
The energy rate is the ratio of total energy to time, which coincides with the definition of power at constant rate:
[tex]\dot W = \frac{\Delta E}{\Delta t}[/tex]
[tex]\dot W = \frac{102.2\,J}{\left(30\,min\right)\cdot \left(60\,\frac{s}{min} \right)}[/tex]
[tex]\dot W = 0.057\,\frac{J}{s}[/tex]
[tex]\dot W = 0.057\,W[/tex]
0.057 joules is needed to create the total rotational energy each second.
