## Requirements and Specifications

Source Code

```import java.util.Scanner; public class App { public static void main(String[] args) throws Exception { // Create scanner Scanner sc = new Scanner(System.in); // Create variables to hold inputs double angle; double speed; double g; // Create variables to hold calculations double speed_mps; double angle_rad; double speed_y; double speed_x; double upward_t; double total_t; double height; double distance; // Display header System.out.println("========= Distance Calculation ========"); // Ask user for angle and speed System.out.print("Enter angle (deg) and speed (mph): "); angle = sc.nextDouble(); speed = sc.nextDouble(); // Ask for gravity System.out.print("Enter gravity (m/s^2): "); g = sc.nextDouble(); // Now, do calculations // Let's be sure that the angle is between 0.0 and 90.0 angle = Math.max(0.0, angle); angle = Math.min(angle, 90.0); speed_mps = speed*1609.34/3600; angle_rad = angle*Math.PI/180; speed_y = speed_mps*Math.sin(angle_rad); speed_x = speed_mps*Math.cos(angle_rad); upward_t = speed_y/g; total_t = 2*upward_t; height = speed_y*upward_t - 0.5*g*Math.pow(upward_t, 2.0); distance = speed_x*total_t; // Now, print System.out.printf("%25s:%11.4f (%s)\n", "Angle", angle, "deg"); System.out.printf("%25s:%11.4f (%s)\n", "Mph", speed, "m/h"); System.out.printf("%25s:%11.4f (%s)\n", "Gravity", g, "m/s^2"); System.out.printf("%25s:%11.4f (%s)\n", "Speed", speed_mps, "m/s"); System.out.printf("%25s:%11.4f (%s)\n", "Radian", angle_rad, "rad"); System.out.printf("%25s:%11.4f (%s)\n", "Vertical Speed", speed_y, "m/s"); System.out.printf("%25s:%11.4f (%s)\n", "Horizontal Speed", speed_x, "m/s"); System.out.printf("%25s:%11.4f (%s)\n", "Upward Duration", upward_t, "s"); System.out.printf("%25s:%11.4f (%s)\n", "Total Duration", total_t, "s"); System.out.printf("%25s:%11.4f (%s)\n", "Height", height, "m"); System.out.printf("%25s:%11.4f (%s)\n", "Distance", distance, "m"); sc.close(); } } ```
