A. An object of mass 500 kg is released from rest 2000 m above the ground and allowed to fall under the inuence of gravity. Assuming the force due to air resistance is proportional to the velocity of the object with proportionality constant b = 50 Nsecfm, determine the equation of motion of the object. When will the object strike the ground? [Hint Here the exponential term is too large to ignore. Use Newton's method to approximate the time twhen the object strikes the ground] Assume that the acceleration due to gravity.r is 9,81 m f secz. v <: let xlt represent the distance object has fallen in t seconds. determine equation of motion object. xm="D">
