A skydiver weighing 170 lb (including equipment) falls vertically downward from an altitude of 13,000 ft and opens the parachute after 18 s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|?|0.55|v| when the parachute is closed and is of magnitude 18|?|18|v| when the parachute is open, where the velocity ?vis measured in ft/s. Assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is...

An object of mass 700 kg is released from rest 1000 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 b=50 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...
