im a college student and i actually didnt attend high school so i've never had any exposure to physics. i've been avoiding it as long as possible but i think the time has come when i should finally attempt it. im very, very scared. i don't know where to begin. I purchased the book Fundamentals of physics by halliday and resnick since it was recommended here alot. i read chapter one and started doing the sample problem...and whoa! i had no idea how they solved it! am i missing something? where should i begin? (not the problem but in understanding physics in general) the problem was: The world’s largest ball of string is about 2 m in radius. To the nearest order of magnitude, what is the total length L of the string in the ball? any help will be appreciated because i want to take organic chemistry II and physics I in the fall semester. i have roughly three months to prepare. thanks!!
