Problem 2: A particle of mass m is released from rest in a constant gravitational field. Assuming that the air drag on the particle varies quadratically with speed, that is

F (v) = c2v2, show that the distance s the particle falls in accelerating from v0 to v1 is given by:
s (v0⇾ v1) = m /2c2 ln (g- c2m2 v20 / g- c2m v21)
