Programming Challenges Question 4

Programming Challenges Question 

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 traveled 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
