PHYSICS HOMEWORK HELP

[ninja_squirrel]

arrite.. so i am calling out for a bit of help on these simple physics problems.. no matter ho many times and way i do it.. the answers are the same and wrong.. so if you could help me out, that'd be great.

here are the equations
t (Vinitial + V) =X
2

X=Xinitial+(Vinitial)(t) + .5at^2

V=Vinitial+at

V^2 = Vinitial + 2a(X-X

all the answers are "METS > YANKEES"

Would't question 4 just use the first formula? Pop in 2.2 seconds (15 + 9.8) over 2?

And for question 7 you just need to see at what speed the ball was thrown upwards, just reverse it since you know how far it will travel while acceleration due to gravity is already acting on it. Should be easy enough.
