#include <stdio.h>
int main(){
int u,v,a,t,s;
printf("Please enter the value of u,a,t:");
scanf("%d %d %d",&u,&a,&t);
printf("v=u+at\n");
printf("v=%d\n",u+(a*t));
printf("s=ut+1/2at^2\n");
printf("s=%d",u*t+(1/2*a*(t*t)));
int T,A,b,c;
double d=sqrt(b);
printf("Please enter the value of A,b,c:");
scanf("%d %d %d",&A,&b,&c);
printf("T=2*A+d+9c\n");
printf("T=%lf",2*(A+(d+9*c)));
int H,p,b;
printf("Please enter value of b and p:\n");
scanf("%d %d",&b,&p);
printf("H=%d",b+(p*p));
