Velocity at a general point P(x, y) for ...

Velocity at a general point P(x, y) for a horizontal projectile motion is given by
`v=sqrt((v_("x")^(2)+v_("y")"^(2))),tan alpha=(v_(y))/(v_(x))`
`alpha`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=-`(1//2)"gt"^(2)`
eliminating t, we get `y=-(1//2)(gx^(2))/(u^(2)`
