1. When a particle falls though the air, its initial acceleration a=g diminishes until it is zero, and thereafter it falls at a constant or terminal velocity vf. If the variation of the acceleration can be expressed as a=(g/v^2f)(v^2f-V62), determine the time needed for the velocity to become v<vf. Initially the particle falls from rest.
