Question

Java:

Create a main method for your class, and then add another method to your class (above the main method) named fallingDistance. This method accepts an integer into its parameter t, which is the amount of time, in seconds, that an object has been falling. This method returns the distance, in meters, that the object has fallen during the time interval. When an object s falling because of gravity, we use the following formula to determine the distance the object falls in a specific time period:

d = ½ gt2

where, d is the distance in meters, g is 9.8, and t is the amount of time in seconds, that the object has been falling.

The method header is shown below:

public static double fallingDistance (int t)

You can test your method by calling it from main method with values of 1 through 10 as arguments and display the return value , or you may leave main empty. Your code with be tested with inputs that produce known outputs.

Answer 1

public class FallingDistance {

    public static double fallingDistance(int t) {
        return 0.5 * 9.8 * t * t;
    }

    public static void main(String[] args) {
        System.out.println("Time\t\tDistance");
        for(int t = 1; t <= 10; ++t) {
            System.out.printf("%d\t\t\t%.2f\n", t, fallingDistance(t));
        }
    }
}
