    Air resistance acting on a falling body can be taken into account by the approximate relation for the acceleration a = (dv/dt) = g-kv, where k is a constant. Derive a formula for the velocity of the body as a function of time assuming it starts at rest.(a=0, t=0) How do you integrate g-kv? Do you need a u substitution?
