'Explanation of each line of code please. I want to understand how to use fsolve() and setting up the equations correctly

b.) Write a program that uses FSOLVE() to solve the Rolling Wheel Dynamics impending slip problem shown. You MUST use the "args feature of Fsolve to communicate the wheel parameters. Use all of the wheel parameters posted, except for the static coefficient of friction and the ramp-angle 0. Generate a plot of ramp- angle vs coefficient of friction for impending slip, for friction values of 0.1, 0.15, 0.2, 0.25, up to 0.85. 17-94. The tire has a weight of 30 lb and a radius of gyration of kg = 0.6 ft. If the coefficients of static and kinetic friction between the wheel and the plane are Ms = 0.2 and Mk = 0.15, determine the tire's angular acceleration as it rolls down the incline. Set 6 = 12. 1.25 ft +EF = m(ac)x; 30 sin 12 - F= 30 jag 32.2 +EF, = m(at)y; N 30 cos 12 = 0 3016 I, G+MG = IGQ; F(1.25) = (62 ) (0.6)*]o Assume the wheel does not slip. 12 SHEDG ag = (1.25) maa N
