• A stone is thrown horizontally at +17 m/s
from the top of a cliff 40 m high.
I.
How long does the stone take to
reach the bottom of the cliff?
t = 2.86 s
II.
How far from the base of the cliff
does the stone strike the ground?
Sx = 48.62 m
III.
What is the speed of the stone just
before it strikes the ground?
|v| = 32.8 m/s
|5y = 5 4y + (v₁) t = -1/2 & 1²
