The first equation of motion is used to calculate the final velocity of an object under constant acceleration.

Algorithm

Without wasting any of your precious time let’s try to understand how the algorithm is implemented.
The first equation of motion is

v = u + a * t

u: initial velocity
t: time taken by the journey
a: constant acceleration

as you can see in our program we are considering u=0 if you want you can set initialVelocity variable value as per your choice or you can ask it from user too, accel=5 and timeOfJourney=7.

In function, finalVelocityWithConstantAcceleration we have implemented the equation.

final_velocity = u * a * i

Code:

   
#include<stdio.h>
  
// this is the implementation of 1st equations of motion.   
void finalVelocityWithConstantAcceleration(int accel,float u,int xtime){  
    float final_velocity=0;  
    printf("Time\tVelocity\\n");  
    for (int i=1;i<=xtime;i++){  
        final_velocity = u + (accel * i);  
        printf("%d s\t%f m/s\n",i,final_velocity);  
    }  
}  
  
int main() {  
    int accel=5;  
    int initialVelocity=0;  
    int timeOfJourney=7;  
    //printf("How much is the initial Velocity of element:");  
    //scanf("%f",&initialVelocity);  
    /* printf("Value of constant acceleration:");  
    scanf("%d",&accel);  
    printf("\n");  
    printf("Value of time:");  
    scanf("%d",&timeOfJourney);  
    printf("\n"); */  
    finalVelocityWithConstantAcceleration(accel,initialVelocity,timeOfJourney);  
 return 0;  
}  

The sample output of this code is.
