Oops.* So it should be"y = Vot + (1/2)at2
Vo = (y - (1/2)at2) / t
Vo = (22 - 0.5*9.80*2.52) / 2.5
Vo = - 3.45 m/s
So Vo is negative because it is going upwards and I chose downwards as positive.
Now I use this in the second equation.* Again choosing down as positive
V = Vo + at
V =...
Can I use y0= 0 and y = 22 if I choose positive as going downwards?
So,
y = Vot + at2
Vo = (y - at2) / t
Vo = (22 - 9.80*2.52) / 2.5
Vo = - 15.7 m/s
So Vo is negative because it is going upwards and I chose downwards as positive.
Now I use this in the second equation. Again choosing down...
It will be up; but I do not know its value. Or is it just Vo?
Can I solve the 2 equations in 2 unknowns now? Is Vo the same for both of the equations?
Thank you!

Wait...is it safe to assume that when they say southwest they mean exactly 45 degrees between west and south?...I am going to bank on that being the case.
