Math Problem 1 - In the play, the Chinese geologist says “Every second four and half pounds of sunlight hits the earth.” But the director wants the writer to change the line to read: “You know, Coronado, there’s been about X pounds of sunlight hitting the earth ever since it began; that’s if you average it out of course”. What is your best estimate of the number the writer should substitute for X?

For purposes of this problem, assume that Sine is right in saying that at this time every second four and a half pounds of sunlight hits the earth. Also assume that sunlight has been the only material altering the weight of the earth (i.e. forget about asteroids hitting the earth or the theory that the moon got created from where the Pacific Ocean is when earth got hit hard in the past.) Do you need Einstein’s equation above, or anything else, to calculate X accurately, given the assumptions made above? What did you actually use to make your estimate?

Assuming your advice to the writer is to put four and a half pounds per second into the revised line, show how you calculated this.

Likely time to solve: 20 min.
