I am coding in c++ a program to calculate for the landing position of a projectile with a given velocity and angle. We are to show the user the landing position only, and save to a document the y position of the object over 30 increments, where one incrememt is the (time of travel / 30)

Here is what my code looks like:

// Projectile Motion

#include

#include

#include

#define pi 3.14159

#define g -9.81

using namespace std;

int main()

{

double landingPoint;

double angle;

double initialVelocity;

double xo = 0.0;

double yo = 0.0;

double vox;

double voy;

double time;

double interval;

double timeStamp;

cout << "Enter the angle at which the projectile is being fired at (in degrees with respect to the positive x-axis): ";

cin >> angle;

while (angle <= 0 || angle >= 90)

{

cout << "Angle must be between 0 and 90."

<< " Re-enter the angle. ";

cin >> angle;

}

cout << "Enter the initial velocity at which the projectile is being fired at (in meters per second): ";

cin >> initialVelocity;

while (initialVelocity <= 0)

{

cout << "Initial velocity must be greater than 0."

<< " Re-enter the initial velocity. ";

cin >> initialVelocity;

}

vox = initialVelocity*cos(angle*pi / 180);

voy = initialVelocity*sin(angle*pi / 180);

time = 2 * voy / g;

interval = time / 30;

timeStamp = 1;

landingPoint = vox * time;

cout << "The projectile will land at x = " << landingPoint << " meters ";

ofstream outFile;

{

outFile.open("loosresults.txt");

outFile << "The y position of the object at time intervals of t/30. ";

for (double interval = 1; interval <= 30; interval++)

for (double timeStamp = 1; timeStamp <= 30; timeStamp++)

outFile << "Time stamp: " << timeStamp << "\t Height: " << (voy*interval) - (.5*g*(interval*interval)) << " ";

}

system("pause");

Here is what my data looks like:

The y position of the object at time intervals of t/30.
