Thanks for the input. I would really like to take something like AP computer science, but as far as I'm aware, AP computer science is generally only offered at private preparatory high schools and schools in the UK. At my school, I was almost suspended for programming on a school PC. Other...

If you're sounding out words letter-by-letter you may want to practice a little, as that isn't really normal. However, it is normal to verbalize the words in your head... they should flow together quickly, though, and the voice in your head should sound like someone speaking at a regular pace...

Sorry if I made it seem like I was in calculus as a junior. That was completely hypothetical. I'm actually in algebra II. Maybe I could take trig over the summer before my senior year, though. That might allow me to take the first CS class which has calculus as a co-requisite. Maybe this will...

Hey everyone, I'm currently a junior in high school and I'm wondering if it would be possible to take a class or two at a community college without a high school diploma. I would like to be able to simply pay for some classes, take them, and leave. I don't want to stay at a community college...

I forgot to square the second time. Thank you very much, you have been a great help. This one really stumped me :rolleyes:

I solved for initial velocity using that simple equation. 0 = vi + (-9.8)(0.4215) 4.1307 = vi Then I plugged that in.

I keep getting a negative number (-1.33) when I plug in initial velocity. I really don't understand this problem, nothing seems to work.

My math background consists of Algebra I and Geometry, so this isn't obvious to me. I think I need to use a system of equations to solve for initial velocity, though... Edit: I used the total time by accident. That helps a lot. Now I need to plug initial velocity into the main equation and...

I must have solved for initial velocity with the wrong equation. I plugged it into my main equation and it was wrong both when I used 1/2 time and given time. I used vf = vi + at This is the best equation I know for this job, so if it's the right one I must be wrong again by assuming final...

Why isn't the initial velocity zero? Are we to assume the guy flies through the floor and up to the highest point?

Thought about that but hesitated to try it. The absolute value of the solution was correct! Thank you very much, Doc Al. I'm still getting used to watching my signs.

I solved this again and got -55.309. This is not correct, and neither is its absolute value. I'm confident in my 4th grade order of operations ability, so the problem probably lies in how I set this up. Here is what I solved: \Deltax = 27(7.1) + 1/2(-9.8)(7.1)2 \Deltax = -55.309 Incorrect

Homework Statement A basketball player achieves a hang time of 0.843 s in dunking the ball. What vertical height will he attain? The acceleration of gravity is 9.8 m/s2. Answer in units of m. Homework Equations I'm not sure what to use, but I think \Deltax = vit + 1/2 at2 could work. The...

We're using a web application that checks the answers for us, and I got it wrong when I entered what I got. I'll try again with the same method, though. I may have messed up the signs, but I also feel like this problem takes more than just plugging into an equation.
