The total distance travelled by vehicle in ‘t’ seconds is given by distance = ut+1/2at² where ‘u’ and ‘a’ are the initial velocity (m/sec.) and acceleration (m/sec²). Write C program to find the distance travelled at regular intervals of time given the values of ‘u’ and ‘a’. The program should provide the flexibility to the user to select his own time intervals and repeat the calculations for different values of ‘u’ and ‘a’.

Description:

The total distance travelled by vehicle in 't' seconds is given by distance = ut+1/2at² where 'u' and 'a' are the initial velocity (m/sec.) and acceleration  (m/sec2)

Algorithm:

Step 1: Start
Step 2: Read interval as integer
Step 3: for counter: 1 to interval increment counter by 1
        begin
            Read time, velocity, acceleration
            Distance += (velocity * time + (accelerations * pow(time, 2)) / 2);
        end
Step 4: Print Distance
Step 5: Stop

Flowchart:

Program:

#include<stdio.h>
#include<conio.h>
#include<math.h>
void main()                      e
{
   int i, n, sec;
   float d, u, a;
   clrscr();
   printf("Enter the no. of intervals\n");
   scanf("%d", &n);
   for(i = 1; i <= n; i++)
   {
      printf("interval: %d \n", i);
      printf("Enter the time in seconds \n");
      scanf("%d",&sec);
      printf("Enter the velocity \n");
      scanf("%f", &u);
      printf("Enter the acceleration \n");
      scanf("%f", &a);
      d= d + (u * sec + (a * (pow(sec, 2))) / 2);
   }
   printf("Total distance travelled is  %.2f", d);
   getch();
}
