Solve the problem.The velocity of a body of mass m falling from rest under the action of gravity is given by the equation 
where k is a constant that depends on the body's aerodynamic properties and the density of the air, g is the gravitational constant, and t is the number of seconds into the fall. Find the limiting velocity, limt?? v, of a 320 lb. skydiver (mg = 320) when k = .006.
