If an object with mass m is dropped from rest, one model for its speed v after t seconds, taking air resistance into account, is mg v = -(1 – e cdm) where g is the acceleration due to gravity and c is a positive constant. (a) Calculate lim,-- v. What is the meaning of this limit? (b) For fixed t, use l'Hospital's Rule to calculate lim.o+ v. What can you conclude about the velocity of a falling object in a vacuum?
