PRACTICE EXERCISES
A pebble is thrown horizontally at
a speed of 5.0 m/s from the top of a
condominium 78.4 m high.
How long does it take the pebble
to reach the ground?
b. How far from the base of the
condominium does the pebble
hit the ground?

a.
с.
What are the horizontal and
vertical components of the
pebble's velocity just before it
hits the ground?
Repeat Problem #1 but this time use
10.0 m/s as the pebble's horizontal
speed.
Repeat Problem #1, but this time
use 156.8 m as the height of the
condominium.
