i havnt made an attempt considering i am extremely lost and do not know where to begin, can anyone give me a hint on where to start?

A good point to start is to read the textbook and find the right equations. That implies some effort to understand what is going on.
There is no acceleration on the x direction (assuming that by x you mean the horizontal direction). The acceleration g is along the y (vertical) direction.
