when a particles falls through the air, the initial acceleration a=g diminishes until it is zero and thereafter it falls at a constant or terminal velocity vf. if this variation of the acceleration can be expressed as a=(g/vf^2)(vf^2-v^2). determine the time needed for the velocity to become v=vf. initially the particles falls from rest.
