Problem 22.4

The growth of populations of organisms has many engineering and scientific applications. One of the simplest models assumes that the rate of change of the population p is proportional to the existing population at any time t: dp dt = kg p (P22.4.1) where kg = the growth rate. The world population in millions from 1950 through 2000 was t 1950 1955 1960 1965 1970 1975 p 2560 2780 3040 3350 3710 4090 t 1980 1985 1990 1995 2000 p 4450 4850 5280 5690 6080 (a) Assuming that Eq. (P22.4.1) holds, use the data from 1950 through 1970 to estimate kg. (b) Use the fourth-order RK method along with the results of (a) to stimulate the world population from 1950 to 2050 with a step size of 5 years. Display your simulation results along with the data on a plot.
