Question
write a C program to find the kinetic energy on an object in motion is expressed as where K = kinetic energy of an object, m = mass of object, v = velocity of object. The work done by a force pushing on an object in the direction of the object’s motion is W = Fs, where W = Work done by the force, F = force on the object, s = distance traveled by the object during the time the object is pushed. For an object pushed horizontally from rest, K = W, so that Assume that one person can push with the force of 0.8 kN and that we have a car of mass m = 1000 kg. Write a program that can complete the following table:
Distance pushed (m)
Final velocity (m/sec)
No. of people required to push

Explanation / Answer
#include<stdio.h>
#include<math.h>
int main(){
double d,v,n,m,f,s;
double k;
m = 1000;
f = 0.8;
printf("Enter final velocity : ");
scanf("%lf",&v);
printf("Enter distance pushed : ");
scanf("%lf",&s);
n = (0.5) * m * v * v * (1/s)*(1/(f*1000));
printf("Number of people : %lf ",n);
printf("Enter final velocity : ");
scanf("%lf",&v);
printf("Enter number of people : ");
scanf("%lf",&n);
s = (0.5) * m * v * v * 1/(n * f * 1000.0);
printf("Distance pushed : %lf ",s);
printf("Distance pushed : ");
scanf("%lf",&s);
printf("Enter number of people : ");
scanf("%lf",&n);
v = sqrt(((s * n * 800)* 2)/m);
printf("Final velocity : %0.2lf",v);
}
