If a projectile such as a bullet or a rocket is fired vertically, the only force acting on it is the force due to gravity. A force balance yields the equation: d?x R2 dt? = -g (R + x)? Where x is the vertical distance measured from the surface of the earth in meters. Ris the radius of the Earth = 6.4*10° m, g is the acceleration due to gravity 9.81 m/s2. Model this equation using Simulink. Display a graph of the projectile height, x, as a function of time. Assume that the initial height is 0, and the initial velocity is 1000 m/s (dx/dt = 1000 at time=0).
