    1. The problem statement, all variables and given/known data
    A blimp of mass 110 kg is pulled at an angle of 52 degrees downwards with respect to the horizontal for D=7 km on level ground at a constant velocity v=14 m/s. If the coefficient of drag (K in F=Kv^2) is 0.5 kg/m, how much work is done by the person pulling?

    2. Relevant equations

    3. The attempt at a solution
    I don't even know where to begin! So confused.
