If the effects of atmospheric resistance are accounted for, a falling body has an acceleration defined by the equation a = 9.81[1-v^2(10^{-4})] m/s^2, where is v in m/s and the positive direction is downward. if the body is released from rest at a very high altitude, determine (a) the velocity when t = 5 s(b) the body’s terminal or maximum attainable velocity (as t→[infinity]).
