PROGRAM Projectile

IMPLICIT NONE

REAL, PARAMETER :: g = 9.8

! acceleration due to gravity

REAL, PARAMETER :: PI = 3.1415926! you know this. don't you?

REAL :: Angle

! launch angle in degree

REAL :: Time

! time to flight

REAL :: Theta

! direction at time in degree

REAL :: U

! launch velocity

REAL :: V

! resultant velocity

REAL :: Vx

! horizontal velocity

REAL :: Vy

! vertical velocity

REAL :: X

! horizontal displacement

REAL :: Y

! vertical displacement

WRITE(*,*) 'Input angle in degree'

READ(*,*) Angle

WRITE(*,*) 'Input time to flight'

READ(*,*) Time

WRITE(*,*) 'Input launch velocity'

READ(*,*) U

Angle = Angle * PI / 180.0

! convert to radian

X = U * COS(Angle) * Time

Y = U * SIN(Angle) * Time - g*Time*Time / 2.0

Vx = U * COS(Angle)

Vy = U * SIN(Angle) - g * Time

V = SQRT(Vx*Vx + Vy*Vy)

Theta = ATAN(Vy/Vx) * 180.0 / PI ! convert to degree
