help me with this C program please!!?

Question

The formula for updating the y-position is

y = y + vy * DELTA_T ;



where vy is the vertical velocity, and we assume that at time zero y is 0. The vertical velocity is updated by



vy = vy - g * DELTA_T


(g = 9.8)


now can u write me a c program that update values of vy and y as shown in equations above. we have to use for or while loops but i m confused.

Answer 1

double y = 0; // time zero y is 0
double vy = somestartvalue;
double g = 9.8;
int t = 0;
int endTime = someStopTime;

for ( t = 0; t < endTime; t++ )
{
printf( "Time: %d - Y: %f VY: %f\n", t, y, d );
y = y + vy * (double)t;
vy = vy - g * (double)t;
}
