Answer:
Did you get the condition exactly correct? Check below.
Did you get the condition exactly correct? Check below.
The program so far:
import java.util.Scanner;
// User picks ending value for time, t.
// The program calculates and prints
// the distance the brick has fallen for each t.
//
class FallingBrick
{
public static void main (String[] args )
{
final double G = 9.80665; // constant of gravitational acceleration
int t, limit; // time in seconds; ending value of time
double distance; // the distance the brick has fallen
Scanner scan = new Scanner( System.in );
System.out.print( "Enter limit value: " );
limit = scan.nextInt();
// Print a table heading
System.out.println( "seconds\tDistance" ); // '\t' is tab
System.out.println( "-------\t--------" );
t = 0 ;
while ( t <= limit )
{
// calculate distance
// output result
t = t + 1 ;
}
}
}
The loop body will execute for t = 0, 1, 2, ..., limit.
At the end of the last execution, t is changed to (limit+1).
But the conditional expression will not allow execution
back into the loop body when t is (limit+1).
Now let us calculated the distance for each value of t using the formula:
distance = (1/2)*G*t2
Translate the formula into a Java statement to fill the first blank.
Fill in the two blanks. Use a tab character in the output statement. Watch out: there are two traps!
