Calculating Range: Zero Air Resistance, Baseball

[1irishman]

Homework Statement

zero air resistance. baseball player hits ball at angle theta above the horizontal at a initial velocity of "z" m/s...how does one calculate range and max height given the fact that the ball lands several metres above where it was originally hit?

Homework Equations

d= vit + 1/2at^2 i think?

The Attempt at a Solution

i need a hint or two please?

 

[gamer_x_]

three hints:

-in which axis is "range" measured?
-what forces do you have acting in this axis?
-based on these forces, formulate your acceleration and displacement equations.
