Hi Friend,

Try the following code:

import java.util.*;
import java.text.*;
class CalculateHeight{
public static void main(String[] args){
DecimalFormat df = new DecimalFormat("##.00");
Scanner input=new Scanner(System.in);
System.out.print("Enter constant rate:");
double g=input.nextDouble();
System.out.print("Enter time:");
double t=input.nextDouble();
double speed=g*t;
double h=speed*t;
double height=h/2;
System.out.println("Rocket reaches at the height of: "+df.format(height)); 
}
}

Thanks
