If you do not consider air resistance, gravity causes a falling object to descend a distance of (9.8)t2 where t is the time in seconds. If a 16 pound bowling ball is dropped from the tallest building in the world, how many meters does it fall during the 4th and 5th seconds combined.

MATH 
bobpursley,
find the total distance in 5 seconds.
then find the total distance in 4 seconds.
subtract one from another. 
MATH 
Steve,
I'd subtract the distance fallen in 3 seconds, leaving the combined total of seconds 4 and 5. :)
