Work done by air resistance

  1. Nov 14, 2009 #1
    1. The problem statement, all variables and given/known data

    a .459kg raindrop falls vertically at constant speed under the influence of gravity and air resistance. acceleration due to gravity is 9.8 m/s

    after the drop 141 m, the work done by gravity is 634.246 J

    a problem ask the work donde by air resistance
    the work done by gravity is 634.246J

    2. Relevant equations

    i just know regular force and work

    w=f*change in x/y
    f= m*g

    3. The attempt at a solution

    i dont know what to do

    Hi PepeF.! :smile:

    Hint: use the work-energy theorem …

    total work done = change in kinetic energy :wink:
