Physics: Finding Runway Length
The code has been modified slightly and now uploaded to the site.

212.cpp
#include <iostream>
#include <math.h>
using namespace std;
int main(){
double speed;
double acceleration;
double length;
std::cout << "Enter speed and acceleration: \n";
std::cin >> speed;
std::cin >> acceleration;
length = (pow(speed, 2)) / (2 * acceleration);
std::cout << "The minimum runway length for this airplane is " << length;
}
