Using kinematics expression of vertical velocity (in y direction) for an accelerated motion (constant acceleration, which is gravity):
Now we need to find as a function of
. We use the horizontal velocity, which is always the same as follow:
We know the angle at 3 seconds:
Substitute in
and then solve for
With this expression we go back to the kinematic equation and solve it for initial speed
