Develop the program calculateHeight, which computes the height that a rocket reaches in a given amount of time. If the rocket accelerates at a constant rate g, it reaches a speed of g Ã?Â· t in t time units and a height of 1/2 * v * t where v is the speed at t.

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
