Projectile motion only provided acceleration diatance

TL;DR Summary: Find initial vertically upward speed of the ball
Find horizontal speed of the speed
Find angle

How to:
Find initial vertically upward speed of the ball
Find horizontal speed of the speed
Find angle

Photo of a printed physics problem with handwritten annotations: a ball launched diagonally upward, a 2.4 m horizontal distance, a maximum vertical displacement of 4.9 m, and constant horizontal speed; three questions follow asking for initial vertical speed, horizontal speed, and launch angle.

i try to solve it but it didn't work

Handwritten projectile motion sketch on grid paper: a parabolic arc with a vertical arrow labelled 4.9 and a horizontal span labelled 2.4, followed by a = 0, Sx = 4.9, Sy = 2.4, Ux = and Sx = Uxt + 1/2 at^2 with 4.9 = Ux.

1. You have mixed up vertical and horizontal displacements.
2. The given vertical displacement is from launch to max height, but the given horizontal displacement is for the whole trajectory.
3. Only the horizontal acceleration is zero. You need an equation involving vertical acceleration.

Same problem but different numbers, hence no duplicate.
