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 -

    find the total distance in 5 seconds.
    then find the total distance in 4 seconds.

    subtract one from another.

  • MATH -

    I'd subtract the distance fallen in 3 seconds, leaving the combined total of seconds 4 and 5. :-)
