+//===========================================================================================
+//INPUT DATA
+THETA=45//                ANGLE OF INCLINATION IN DEGREES
+g=9.81//                   ACCELERATION DUE TO GRAVITY IN N/mm^2
+U=.1//                     COEFFICIENT FRICTION
+//Rn=NORMAL REACTION
+//M=MASS IN NEWTONS
+//f=ACCELERATION OF THE BODY
+u=0//                      INITIAL VELOCITY
+V=10//                     FINAL VELOCITY IN m/s^2
+//===========================================================================================
+//CALCULATION
+//CONSIDER THE EQUILIBRIUM OF FORCES PERPENDICULAR TO THE PLANE
+//Rn=Mgcos(THETA)
+//CONSIDER THE EQUILIBRIUM OF FORCES ALONG THE PLANE
+//Mgsin(THETA)-U*Rn=M*f.............BY SOLVING THESE 2 EQUATIONS 
+f=g*sind(THETA)-U*g*cosd(THETA)
+s=(V^2-u^2)/(2*f)//                  DISTANCE ALONG THE PLANE IN metres
+//==============================================================================================
+//OUTPUT
+printf('DISTANCE ALONG THE INCLINED PLANE=%3.3f m',s)
