Homework Statement Hello. I was wondering if you guys could help me tell me why i am getting this problem wrong. Two airplanes taxi as they approach the terminal. Plane 1 taxies with a speed of 12.1 m/s due north. Plane 2 taxies with a speed of 6.3 m/s in a direction 21.2° north of west...

you are correct, now that i got my initial velocity of 10.04m/s, g = -9.80m/s^2, x0= 0 and time crossing power line =0.85 i used x = x0 + V0 * t + 1/2*g*t^2 x = 0 + (10.04m/s)(0.85s ) + 1/2 (-9.8m/s^2)(0.85)^2 = 4.994 m How does that look?

oh you are correct! I'm dyslexic! :( I resolved the problem and got 10.04m/s for my initial speed which is correct. However, my distance of 5.148m is still wrong. Any ideas?
