the distance covered by a falling ball varies as the square of the time taken.if a ball falls through 1800m in 15seconds,calculate the distance when the time taken is 15seconds and the time taken for is distance of 648m.?

  • mathvariation! Pls I need help! 2(steve,reiny,reed)pls -

    (d/1800)=(t/15)^2
    648/1800=t^2/225

    t= sqrt(225*648/18OO)

    That is the time to fall 648 meters.

    The distance taken in 15 seconds is 1800m, that was given.
