Write a program to input the initial velocity, acceleration and time travelled. Calculate the
Program 2
distance travelled by the body.
1 import java.util.*;
2 class distance_travelled
3 {
4 public static void main ()
5 {
6 Scanner sc= new Scanner (System.in);
7 double u,t,a,s;
8 System.out.print("Enter initial velocity: ");
9 u=sc.nextDouble();
10 System.out.print("Enter the acceleration of the body: ");
11 a=sc.nextDouble();
12 System.out.print("Enter the time travelled: ");
13 t=sc.nextDouble();
14 s=(u*t) +1.0/2.0*a*Math.pow(t,2);
15 System.out.println("The distance travelled: "+s+" km ");
16 }
17 }
You will get the following output:
Program 3 Write a program to input the side of a equilateral triangle and calculate the area.
1 class equilateral
2 {
3 public static void main (double s)
4 {
5 double a;
6 a = Math.sqrt(3)/4.0*s*s;
