Hello. Im stuck on this physics problem that i have for homework. Its the wording of the question thats odd to me. Im not sure exactly where to begin. So after one century, the length of each day will be 24 hours and .001 s? And after the second century the length of each day will be 24 hours and .002 s? Is there a quicker way to do this than doing a 20-step summation!!?!? I started off by multiplying .001 x 365, because that will give you the total amount of added time after a year ... however after that it would be long summation, and Im sure that there must be a quicker way. (FYI, the answer is 2 hours if you want to check your work :P) thanks in advance for any help/leads.
