Question

Equations of Motion Revisited with Methods (20 points) u at 2. s ut at 3. v u as Redo the question from Assignment 1 by using methods. Your program must have three methods for olving each of the three equations respectively solveEanl method receives the u, a and t as arguments, and returns value v. solve Eqn2 method receives the u, a and t as arguments, and returns value s solveEqn3 method receives the u, a and s as arguments, and returns value of v2. Note: Be careful with data type of arguments and the return type of methods.

Explanation / Answer

import java.text.DecimalFormat;

public class Motion {
  
   public static double solveEqn1(double u, double a, double t){
       return u + a*t;
   }
  
   public static double solveEqn2(double u, double a, double t){
       return u*t + (0.5*a*t*t);
   }
  
   public static double solveEqn3(double u, double a, double s){
       return u*u + 2*a*s;
   }
  
   public static void main(String[] args) {
       // to format double value upto 2 decimal point
       DecimalFormat df = new DecimalFormat("#.00");
      
       double u = 12.5;
       double t = 2.5;
       double a = 3.4;
      
       double v = solveEqn1(u, a, t);
       double s = solveEqn2(u, a, t);
       double vsq = solveEqn3(u, a, s);
       System.out.println("Value of v: "+df.format(v));
      
       System.out.println("Value of s: "+df.format(s));
      
       System.out.println("Value of v square : "+df.format(vsq));
   }

}

/*

Output:

Value of v: 21.00
Value of s: 41.88
Value of v square : 441.00

*/
