Given:
The horizontal velocity is v=18 m/s.
The height of the cliff is y=50 m.
Part (a)
as there is no horizontal distance so there is no initial horizontal position and the height of the cliff is the initial vertical position.
Thus, the horizontal position is:
x=0 m.
The vertical position is:
y=50 m.
