3. The air resistance of a free falling body with mass m is assumed to be proportional to its current speed v: Fs = cv, where c is a coefficient of proportionality. a) Describe the dependence of the speed with time v(t) if at time t=0, the speed is zero v(0) = 0. b) If m=20kg and c=2.4, calculate the speed of the free falling body at t=8s.
