An inclined plane makes an angle $θ = 45^{\circ}$ with horizontal. A stone is projected normally from the inclined plane, with speed $u m / s$ at $t = 0$ (as shown in the figure). x and y-axis are drawn from point of projection along and normal to inclined plane as shown. The length of incline is sufficient for the stone to land on it and neglect air friction.
