The range on the inclined plane, Physics

A projectile is projected with speed u at an angle of 60 degrees with the horizontal from the foot of an inclined plane.If the projectile hits the plane horizontally,the range on the inclined plane will be:

Ans) Time = 1/2 . time of flight=usin(o)/g=u.sin60/g

x axis distance = ucos60.t=ucos60.usin60/g=(u^2)sin60.cos60/g

distance on y=H(max)=(u^2)sin^2 (60)/2g

Hence total displacement=Range on inclined plane=root(x^2+y^2)=root(21)u^2/8g
