A 320-lb object is released from rest 400 ft above the ground and allowed to fall under the influence of gravity. Assuming that the force in pounds due to air resistance is-20, where is the velocity of the object in ft/sec, determine the equation of motion of the object. When will the object hit the ground? Assume that the acceleration due to gravity is 32 /sed and let x) represent the distance the object has fallen in t seconds Determine the equation of motion of the object
