Work done by the Sun on the Earth

The Earth takes 1 year to complete its orbit around the Sun. Treating the orbit as perfectly circular, find the net work done on the Earth by the Sun in 14\frac14 of a year. Give your answer to three significant figures.

Assumptions:

Mass of the Earth = 5.97×1024kg5.97\times 10^{24} \text{kg}

Distance from Sun to Earth = 1.50×1011m1.50\times 10^{11} \text{m}

1 Earth year = 365 Earth days

1 Earth day = 24 hours
