The density of air is p = 1.22 kg m-3 and the coefficient of drag for a sphere is C = 0.47. Make a plot of the trajectory of the cannonball (i.e., a graph of y as a function of x). = a RPC * V *2 + ja, 2m y = -8 aR2PC 2m F V *2 + y2, Change these two second-order equations into four first-order equations using the meth- ods you have learned, then write a program that solves the equations for a cannonball of mass 1 kg and radius 8 cm, shot at 30 to the horizontal with initial velocity 100 ms-1.
