"College Physics I"

Algebra based.

This might do better in Tilted Knowledge, but whatever.

I really don't remember that much about physics, but I'd think that part B would be exactly the same except that your v0 (v-nought or v-initial, however you notate it) would be 4.00 m/s. The same acceleration would apply, etc.

Actually, working a couple of steps back from your final answer, you made an algebra mistake. When you went from 59.2 + 1/2... to 118.4... you didn't distribute the times two correctly. For your last line you should have had 118.4036 + 16 = Vf^2

Answer? 11.5932

That's it! Wow, thank you. I can't believe I did that - I have re-done those very operations twice.

damn it, i was refreshing the page to see if dieseldog had responded, and the solution was already posted !

hey, if you want some more resources, check out my teacher's page on it -

Is this your actual homework paper? Your handwriting is disturbingly neat and legible. Anything math-related turns into a cryptic jumble of numbers when I do it. My poor teachers.

Yeah, it was the actual paper. It's more tidy than my average page, though.
