Homework Help: Finding mass with acceleration and velocity

  1. Nov 7, 2009 #1
    1. The problem statement, all variables and given/known data

    the force of air resistance on a raindrop is 5.3x10-5N when it falls with a erminal velocity of 5.3 m/s.

    the acceleration of gravity is 9.8 m/s2.

    what is the MASS in Kg of the raindrop?

    [i am completly lost in this one]
