Unformatted text preview: below assuming that the engine imparts a force u as shown in the figure. Assume that the rotational inertia of the wheels is negligible. u (force developed by the engine) Assume that there is friction retarding the speed is proportional to the speed with a coefficient b. Assume m is mass of the car Write the equation in terms of velocity (v) b) Take the Laplace transform of the differential equation c) What is the transfer function between the input u and output velocity v d) Use MATLAB to find response of the velocity of the car for a step input of u=500N, if m=1000 kg, and b= 50N.sec/m...
