find initial velocity with the given: time=1.37s, gravity accelaration=-9.8m/s^2,distance=-1.0m
its about projectiles but im using one of the kinematics formula d=vi(t)+(1/2)(a)(t)^2 to find initial velocity but im having hard time with it.

A ball is launched at speed Vo with an angle to the horizontal. At its maximum height h, it has half the speed as when it was at half this height (h/2)
What is the angle it was launched at? Been stuck on this problem for quite some time now. Any guidance would be great, thanks!
