When a particle falls through the air, its initialacceleration a = g diminishes until it is zero, and thereafter itfalls at a constant or terminal velocity vf. If thisvariation of the acceleration can be expressed as a =(g/vf^2)(vf^2 - v^2), determine the timeneeded for the velocity to become v < vf . Initiallythe particle falls from rest.
