Write a program that asks the user to enter an object’s mass, then calls a // function to return the object's weigh in newtown. If the object weighs // more than 500 newtons, the function also displays a message indicating that // it is too heavy. If the object weighs less than 100 newtons, the function // also displays a message indicating that it is too light.

Answer:

import java.util.Scanner;

public class num8 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter the mass");

       double mass = in.nextDouble();

       double weight = calWeight(mass);

       System.out.println("The weigth is "+weight);

   }

   static double calWeight(double mass){

       double weight = mass*9.80665; // assume a = accelation due to gravity = 9.80665N

       if(weight>500){

           System.out.println("Too Heavy");

       }

       else if(weight<100){

           System.out.println("Too Light");

       }

       return weight;

   }

}

Explanation:

  • Using Java programming language
  • The main method is created to request and store a variable, mass in kilogram. The main method call calWeight() and passes the value for mass
  • A method calWeight() is created that calculates the weight in newtons (mass * 9.8).
  • The method checks if the weight is greater than 500 (prints too heavy) if less than 100(prints to light)
  • Returns the weight
