Step 2: Enter the known values. Define z0 and y0 as 0. Notice that
the menu labels turn black as you store values.

Step 3: Solve for the velocity, vy. Notice that pressing the left-shifted
version of a variable's menu key causes the HP 48 to solve
for it.

Step 4: Recall the range, R, divide by 2 to get the halfway distance,
and enter that as the z-coordinate. Notice that pressing the
right-shifted version of a variable's menu key causes the
HP 48 to recall its value to the stack. (The small square next
to the FE on the menu label indicates that it was used in the
previous calculation.)
Step 5: Solve for the height y. Notice that the HP 48 finds values
for other variables as needed (shown by the small squares) in
order to solve for the specified variable.
