Free fall One possible model that describes the free fall of an object in a gravitational field subject to air resistance uses the equation v'(t) = g – bv, where v(t) is the velocity of the object for t > 0, g = 9.8 m/s² is the acceleration due to gravity, and b > 0 is a constant that involves the mass of the object and the %3D air resistance. a. Verify by substitution that a solution of the equation, subject to the initial condition v(0) = 0, is v(t) = (1 - e). b. Graph the solution with b = 0.1 s. c. Using the graph in part (b), estimate the terminal velocity lim v(t).
