Best I can do is to ignore air resistance. A football is a tough thing to model because of its shape. Was the kick a spiral, or was it end-over-end? Makes a big difference.
But if we ignore air resistance, we can do the problem. First break the initial velocity into components.
vox = 22 cos 34 = 18.23 m/s
voy = 22 sin 34 = 12.30 m/s
To see how long it's in the air, use
s = (1/2) gt^2 + voy t = 0 (where g = -9.8 m/s/s)
s = -4.9 t + 12.30 = 0
t = 2.51 sec. (time aloft)
Max height will be at t = 1.26 sec:
s = -4.9 (1.26^2) + 12.30(1.26) = 7.72 m (max ht.)
Distance s = (vox m/s)(t sec) = 18.23 x 2.51 = 45.76 m (range)

You need the mass of the object in order to find the gravitiional pull which inturn will tell you the arc range. Once that is found then the max height and lenght of time airborn can be found.
