An object of mass 700700 kg is released from rest 20002000 m above the ground and allowed to fall under the influence of gravity. Assuming the force due to air resistance is proportional to the velocity of the object with proportionality constant bequals=5050 N-sec/m, 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 t when the object strikes the ground.] Assume that the acceleration due to gravity is 9.81 m divided by sec squared9.81 m/sec2.
