Chapter 2, Problem 1E

Explanation of Solution

Code for declaring variables

  • A declaration of a variable is where a program says that it needs a variable.
  • The declaration gives a name and data type for the variable.
  • A variable cannot be used in the program unless it has been declared.
  • It also asks for a particular value that can be placed in the variable.
  • Hence the code for declaring variables s0,v0,a and t is

 double s0 = 12.0;

 double v0 = 3.5;

 double a = 9.8;

 double t = 10.0;

  • The code for computing s on the basis of these values is

 double s = s0 + v0 * t + 0.5 * a * t * t;

 System.out.println(s);
