Second Equation of motion, How to implement using C language

The second equation of motion is used to calculate the displacement 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 second equation of motion is

s = u*t + 1/2 * a * t * t

s: total displacement
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 also acceleration value is 9.8 equal to the gravity of earth.

In a function fallingDistance we have implemented the equation.

total_dist = 9.8 * i * i * 1/2 + u * i ;

total_dist = (4.9 * i * i) + (u * i);


Code:

 
#include 

// this is the implementation of 2nd equations of motion. 
void fallingDistance(int x,float u){
    float total_dist=0;
    printf("Time\tDistance\n");
    for (int i=1;i<=x;i++){
        total_dist = (4.9 * (i*i)) + (u * i);
        printf("%d s\t%f m\n",i,total_dist);
    }
}

int main() {
    int fallingTime=0;
    int initialVelocity=0;
    //printf("How much is the initial Velocity of element:");
    //scanf("%f",&initialVelocity);
    printf("How much seconds element is in air:");
    scanf("%d",&fallingTime);
    printf("\n");
    fallingDistance(fallingTime,initialVelocity);
 return 0;
}

The sample output of this code is.

C/C++ program to check the Palindrome string.

Image
Palindrome string: A string or word which are same from the start and end means word or program which look like same as original and reversed. To do that we have to first reverse the string. Check out our post on the String reverse in C/C++. To write the program of the Palindrome steps used are. Get the input from the user. convert the string to the Lower case to avoid any case sensitivity. apply the logic of the reverse the string. compare the reversed and original string, if same then the string is a palindrome. if different string is not a palindrome. print the result to the user. without wasting much time lets start. First of all the C schema. #include <stdio.h> #include <string.h> #include <ctype.h> int main(int argc, char const *argv[]) { return 0; } ctype.h is used to get the advantage of the function tolower() later in the program. Now take the input from the user. char name[150],rev[150] ; int l=0; printf("Enter a string to check palindrome\n");

Third Equation of motion, How to implement using C language

Image
The third equation of motion is used to deduce the relation between initial velocity, final velocity, displacement, and acceleration without time. Third equation of motion Algorithm: Without wasting any of your precious time let's try to understand how the algorithm is implemented. want to check the implementation of Second equation of motion , click here. Third equation of motion is v * v = u * u + 2 * a * s s: total displacement u: initial velocity v: final velocity a: constant acceleration In function CalculateDisplacement, we are calculating the value of displacement. want to check the implementation of First equation of motion, click here. 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. Code: #include stdio.h //please make it correct // this is the implementation of 3rd equations of motion. void CalculateDisplacement(float a,float u,float v){ float displacement=
