h = -vo*t + 1/2*g*t^2and i plugged 30 meters in for h. plugged 9.8m/sec^2 for g. and 3 seconds for time

ok thanks berkeman. i got 4.7m/sec as intial velocity. could you confirm that?

is the intial velocity on my problem 4.7 m/sec? that is what i ended up getting

what?

ok no << profane insult removed by berkeman >>im 17. and clearly it doesn't matter if you don't believe me. don't write **** down on my thread if your not going to help out.

Im in twelvth grade in high school and i have only been taking physics for 3 weeks. and i guess i put this problem in the wrong folder cause its not homework. my teacher couldn't figure out how to do it so he asked me to try

hey rl.bhat if you could help me out with solving this it would be good. i don't have enough experience in physics to know what h would be?

well i had no idea how to attempt it. i tried for like an hour on scratch paper then found this. so if you know how to do the problem then be my guest
