I have decided to go home schooled for my last two years of high school and I am trying to make a curriculum at the moment. Do any of you know a good resource for this? It has not been too hard to find a physics 1 or 2 course, but calculus based physics courses have been pretty sparse. So far I...

The person who asked this problem meant "by." I just copied the problem down verbatim in case that wasn't the case.

ohhhhh... I completely forgot. So now when I solve the equation, I get about 3.09047 for the initial length. When I put this back into the equation T = 2π√(l/g) I got about 3.525678 seconds. I am not sure if it is correct yet but thanks a lot for the help!

I only put the parentheses around the l/g to show that it was included in the square root. Anyway, you can take a look at my work: Unless I messed it up, the lengths do in fact cancel each other out. :/

What's up? I'm Ethan. I am in my first year of AP Physics, and am the only 10th grader in my class. Physics is probably my most prevalent academic passion, and I hope I can be pretty active here when I am not doing homework like I should be doing right now (lol). Anyway, I hope to see some cool...

To increase the period of oscillation of a pendulum in 1 second, it is needed to increase the length of it in 2 meters. Calculate, in seconds, of the initial period of oscillation of the pendulum. I found this question online a few minutes ago. I have not learned this in physics class yet so...
