Question:
A realistic analysis of free fall considers air drag which tends to counteract the pull of gravity. In such analysis, the acceleration a of a body may be represented as a = g kv2 where g is the gravitational acceleration, k is a constant related to air resistance, and v is the instantaneous velocity of the falling object. Assuming vo = 0, determine v(t).
