Calculating the distance travelled by a car at different time intervals

PROBLEM
Write a program to calculate the distance travelled by a car at different time intervals. The initial velocity of the car is 36 km/hr and the constant acceleration is 5 m/s2.

The formula to calculate distance is:

Distance Travelled = u*t+((a*t*t)/2) where,
u = initial velocity of the car (36 km/hr)
a = acceleration of the car (5 m/s2)
t = time duration in seconds

The program should accept 2 time intervals as the input (one time interval per line) and print the distance travelled in meters by the car (one output per line).

Definitions:
————
1 kilometer = 1000 meters
1 hour = 3600 seconds

Let us suppose following are the inputs supplied to the program

10
8

Then the output of the program will be

350
240

Solution in simple java code


import java.util.Scanner;
class problem4{
public static void calculateDistance(int t1,int t2){
int u = 10; // in m/s
int a = 5; // in m/s2
int distanceTravel1 = u*t1+((a*t1*t1)/2);
int distanceTravel2 = u*t2+((a*t2*t2)/2);
System.err.println(distanceTravel1);
System.err.println(distanceTravel2);
}
public static void main(String args[]){
int firstValue;
int secondValue;
   Scanner in = new Scanner(System.in);
    firstValue = in.nextInt();
secondValue = in.nextInt();
calculateDistance(firstValue,secondValue);
}
}

Note: Input given via Console input(using scanner class).
After run this code via command prompt, you should type two values (one value per line) and then enter. now you can see the output.
