For the case of freefall, explain how to calculate the total distance traveled and the instantaneous velocity for an object that is dropped from rest by applying the fundamental meaning of acceleration and by using the two equations: Vav+(vf+vi)/2 and d=vav+t. Is this method applicable only for the case of freefall and with an initial velocity of zero, or s it always applicable to cases where the acceleration on a object is constant and parallel, or antiparallel, to the direction of motion? Explain.
