Provide an appropriate response.If a body of mass m falling from rest under the action of gravity encounters an air resistance proportional to four times the square root of velocity, then the body's velocity t seconds into the fall satisfies the equation: m = mg - 4kv2where k is a constant that depends on the body's aerodynamic properties and the density of the air.Determine the equilibrium, velocity curve, and the terminal velocity for a 170 lb skydiver (mg = 170) with k = 0.005.
