2.9 (Physics: acceleration) Average acceleration is defined as the change of velocity divided by the time taken to make the change, as shown in the following formula: `a = (v1 - v0)/t` Write a program that prompts the user to enter the starting velocity v0 in meters/ second, the ending velocity v1 in meters/second, and the time span t in seconds, and displays the average acceleration.

import java.util.Scanner;
public class Exersice_09 {
public static void main(String[] args) {
  Scanner input = new Scanner(System.in);
  System.out.print("Enter v0, v1, and t:");
  double v0 = input.nextDouble();
  double v1 = input.nextDouble();
  double t = input.nextDouble();
  double avg = (v1 - v0) / t;
 
  System.out.println("The average acceleration is " + avg);
 
 }
