you are to write a cannon simulation in C++ (NO WAY IN HELL IS JAVA ACCEPTIBLE!) , where the user inputs the initial angle theta, initial velocity is set to 684 meters per second. Use the equations of motion to determine the flight time t and trajectory, in 1 second intervals and store them in a link list, once complete download the x,y positions of the projectile to a file. Open that file with gnuplot and graph
