void readToContent(ifstream *input);
double fix(double inputnumber, int decimals);

int main(int argc, char * argv[]) {

	//For the sake of brevity, I have left off exception handling for now. This function assumes input is formatted correctly.
	if (argc != 3) {	
		cout << "Syntax:\nprogram.exe NameOfInputFile NameOfOutputFile\n\nTerminating.";
		return 1;
	}
	ifstream input;
	ofstream output;
	//open the first argument for reading
	input.open(argv[1],ios::in);
	//open the second arg for writing
	output.open(argv[2],ios::out);
	//The stream will evaluate to false end of file when the end of file is reached.
	while(input) {
		int numcases;
		input >> numcases;
		for(int curcase = 0; curcase < numcases; curcase++){
			double curnum;
			input >> curnum;
			output << "Velocity needed is: " << floor( (100*sqrt(9.8*curnum)) + .5)/100  << endl;
		}
		//Read to content to force loop exit if there is whitespace ending the file.
		readToContent(&input);
		//Sets of test cases delmited with a blank line
		if (input) {output << endl;};
	}
	input.close();
	output.close();
}

void readToContent(ifstream *input) {
		//Skip past whitespace
		char temp;
		do {
			temp = (char) input->get();
		} while ((temp == '\n' || temp == ' ') && input);
		//once we have read non whitespace, decrement so that is read again for >> later
		if (input) {
			input->unget();
		}
}

Only thing I can think of is that my program currently reports one more decimal than in your sample output.

Velocity needed is: 65.22
Velocity needed is: 47.89
Velocity needed is: 47.89

Velocity needed is: 57.89
Velocity needed is: 56.35

The input will consist of an integer representing the number of test cases, followed by the necessary distance, in yards.

Velocity needed is: 65.22
Velocity needed is: 47.89
Velocity needed is: 47.89
Velocity needed is: 4.43
Velocity needed is: 57.89
Velocity needed is: 56.35
