D = Xo * 1.8 = 30 m.
Xo = 30/1.8 = 16.67 m/s=Hor. component of initial velocity.
Y = Yo + g*Tr = 0 at max Ht.
Yo - 9.8*(1.8/2) = 0
Yo - 8.82 = 0
Yo = 8.82 m/s = Ver. component of initial velocity.
a. Vo^2=Xo^2 + Yo^2=16.67^2 + 8.82^2 =
355.7
Vo = 18.9 m/s = Initial velocity.
b. tan A = Yo/Xo = 8.82/16.67 = 0.52909
A = 27.9o
