4. (Inspired by recent eclipse...) If a small body were to orbit a much larger stationary body (e.g. a star), its motion would be governed by the following ODEs: x = GMs(xs-x) [(x-xs)²+(y-ys)2] 3/2 x(0) = xo x(0) = xo GMs (ys-y) ÿ = [(x-xs)²+(y-ys)2]3/2 y(0) = Yo y(0) = yo Where x(t) and y(t) give the position of the small body over time, G is the gravitational constant, Ms is the mass of the large body, and xs and y, specify its fixed position. a) Convert this problem to a system of first order ODEs. b) Assume G = = = 10, Ms 5, xsys = 0 with initial conditions xo == -1, yo = 0, xo = 5, yo = 5 and use ode45 to solve the system until t = 3. You can use the attached code and complete the missing parts. Also include the final plot of the trajectory.
