Two objects are thrown from the top of a tall building. One is thrown up, and the other is
thrown down, both with the same initial speed. What are their speeds when they hit the street?
a. The one thrown down is traveling faster.
b. The one thrown up is traveling faster.
c. They are traveling at the same speed.
d. It is impossible to tell because the height of
the building is not given.
6. A personnel officer drove from Lake Charles to a conference in Baton Rouge. The total
distance for the round trip was 240 miles. The time required to travel one way to Baton
Rouge was two hours. Due to heavy traffic during the return trip to Lake Charles, an extra
hour was required. How much slower was the personnel officer travelling on the return trip?
A. 10 mph slower
B. 15 mph slower
C. 20 mph slower
D. 25 mph slower

5. As I drive on a back-country road, I suddenly see a deer "frozen" in the headlights. I was
driving at 11.4 m/s, but immediately apply the brakes and slow with an acceleration of
3.80 ".
a.
If the deer was 20.0 m from my vehicle when the brakes were applied, how close did
I come to hitting the deer?
b. How much time was needed for my vehicle to stop?
