UVA10071 back to High School Physics

Problem Link: UVA10071 back to High School Physics.

problem Brief : the title of the topic is to revisit high school physics. The particle acceleration is constant, and the input V and t,v are the speed of the t time Point particle, seeking the distance of 2t time point movement.

problem Analysis : Set particle initial velocity is v0, acceleration is a, then T time point speed v=v0+at. Displacement of the 2t time point s=v0*2t+1/2*a* (2t) ^2 (distance from s= v* time t+1/2at^2) =2v0t+2at^2=2t (v0+at) =2vt.

Description of the program:(slightly).

The C language Program of AC is as follows:

/* UVA10071 back to High School Physics */#include <stdio.h>int main (void) {    int V, t;    while (scanf ("%d%d", &v, &t)! = EOF)        printf ("%d\n", 2 * v * t);    return 0;}
