SOURCE CODE:


/*To determine the maximum height,time of flight and horizontal range of a projectile motion*/

scanf("%f",&u);
printf("\nEnter angle of prijection:");

H=u*u/(2*g);
T=2*u*sin(rtheta)/g;

printf("\nThe horizontal range is:%fm\n",R);
printf("\nThe maximum vertical height for angle %f is:%fm\n",theta,h);

}

Algorithm:

1.Start

2.Read the velocity,u

3.Read the angle,theta

4.Calculate maximum height H=u2/2g

5.Calculate the time of flight ,2usin(rtheta)/g

6.Calculate horizontal range,u2sin(2*rtheta)

7.Calculate maximum vertical height,h=H*pow(sin(rtheta),2)

8.Print maximum height,time of flight,horizontal range and vertical height.

9.Stop
