A golfer wants to hit the ball a horizontal distance of 130M and 20M above his tee-off point, but wants the ball to land 10 M below his tee-off point. What is the balls Initial velocity?

S= VoT+1/2AT²

V= Vo+AT

V²=Vo²+2AS

So far I have broken up the graph into 3 Parts...from Point A to Point B i have solved for the Y direction.

Ay= -9.81m/s²

Voy= 19.8m/s

Vx= 0

Sy= 20m

T= 2s

But I cant seem to start off in the X direction...do I go from Point A to C? B to C in the Y direction? im really lost everytime I try to solve another direction from ethier point I have no information to create a solution.

btw the answer is Vo= 35.1 m/s angled at 34.4 so please just help me from understanding how to go from here.
