**osvaldo**, Saturday, June 25, 2011 at 5:55pmV initial for x axis: 1.8

V initial for y axis: 0.0

Acceleration on x axis: 0

Acceleration on y axis:-g=-9.81

Δ time: 3

Y final:0

X initial: 0

looking for: Y initial and X final

eqt 2-11b: Δx=Vi(Δtime)+(a*Δt^2)/2

for x axis:

Δx=Vi(Δt)+ zero (canceled out)

= 1.8(3)=5.4

5.4 m far from base

for y axis:

Δy= zero (canceled)+(a*Δt^2)/2

=(-9.81*3^2)/2

=-44.1

-44.1m is your height of cliff
