An object of mass 20 kg is released from rest and allowed to fall under the influence of gravity. Assume that the force in Newtons due to air resistance is -28v where v is the velocity of the object in m/s. If it is initially dropped from a height of 800 meters, approximately how long will it take to reach the ground? Use x (t) as the distance below the point from where it was dropped.
