Need HELP writing Matlab code

5. A 2.54 cm pipe is to span a 25 m section of a river while submerged in the river. Flow of the river past the pipe will create a drag force on the pipe. A structural analysis of this length of pipe indicates that it can only withstand a maximum force of 150 N. Determine the average velocity, V, of the water that the pipe can withstand using the Secant method. The drag force is given by pV2 F) = CD 2 where p is the density of the water (1000kg/m), V is the average velocity of the water in m/s, and Cp is the coefficient of drag. The drag coefficient follows Cp = 0.193Re0.681 Pr1/3 where Pr is the Prandtl number (14.0 for water) and Re is the Reynolds number. The Reynolds number for flow outside a pipe is Re = PDV/u, where D is the given pipe diameter and u is the viscosity of water (0.02 g/cm-s). Also graph the drag force as a function of average water velocity. Graph for velocity from 0-0.1 m/s and mark the point found with your numerical method
