Passage
Velocity at a general point P (x, y) for a horizontal projectile motion is given by
V = =
The Image is Velocity Graph
α is angle made by v with horizontal in clockwise direction Trajectory equation for a horizontal projectile motion is given by x = v x t = ut
y =- ( ) gt 2
Picture Display is Velocity Graph
Eliminating t, We get y =-
