import java.util.Scanner;

public class PhysicsAcceleration {
    public static void main (String [] args) {

        Scanner input = new Scanner(System.in);
        
        System.out.println("This Program Calculates Average Acceleration.\n");
        
        System.out.println("Enter starting velocity(v0) in meter/second: ");
        double startingVelocity = input.nextDouble();
        
        System.out.println("Enter ending velocity(v1) in meter/second: ");
        double endingVelocity = input.nextDouble();
        
        System.out.println("Enter time(t) in seconds: ");
        double time = input.nextDouble();
        
        double average = (endingVelocity - startingVelocity) / time;
        
        //display result to 4 decimal places
        System.out.println("The average acceleration is " + (int)(average * 10000) / 10000.0);
    }
}
