Chapter 6, Problem 15PP

Program Plan Intro

Simulation of ball

Program plan:

• Create a class “Cannon”,
  • Declare and initialize necessary variables.
  • Define the constructor to assign initial values.
  • Define the function “movem()” to calculate the updated value of position and velocity.
  • Define the getter method “getVel()” to return the velocity.
  • Define the getter method “getPos()” to return the position of the ball.
• Create a class “Cannondri”,
  • Define “main()” function,
    • Create an object for “Scanner” class to get the input from the user.
    • Get the velocity from the user using “next()” method.
    • Initialize the necessary variables.
    • Create an object for “Cannon” class.
    • Execute “do-while” loop whenever the exact position is greater than “0”,
      • Call the function “movm()”.
      • Calculate “t” value.
      • Assign the velocity return from “getVel()”.
      • Increment the “step” value by “1”.
      • Calculate the exact position of the ball.
      • Check whether the “step” value is divided by “100”.
        • Print the position and velocity and exact position of the ball.
