Homework Help: Terminal Velocity of a skydiver

  1. Nov 16, 2014 #1
    1. The problem statement, all variables and given/known data

    A skydiver, initially undergoing a high acceleration, is approaching her terminal velocity. At a given
    instant, the fluid friction (due to air resistance) on the diver and her diving gear is 680. N [up] and the
    unbalanced force causing the acceleration is 40. N [down]. Find the mass of the diver with her gear.

    2. Relevant equations

    3. The attempt at a solution

    My attempt: Fg = mg
    4.08 kg =m

    Your diver has a force acting against gravity. The net force is 40N, how would you find the gravitational force knowing the net and frictional force?
