Velocity in a Resisting Medium The velocity v of an object falling through a resisting medium such as air or water is given by Voke-kr 32 V = k e-kt + 32 where vo is the initial velocity, t is the time in seconds, and k is the resistance constant of the medium. Use L'Hôpital's Rule to find the formula for the velocity of a falling body in a vacuum by fixing v, and t and letting k approach zero. (Assume that the downward direction is positive.)
