A particle is projected horizontally with speed $$u$$ from a point A which is $$10 m$$ above the ground. If particle hits the inclined plane perpendicularly at point B. ($$g=10 ms^{-1})$$

Q1. Find the horizontal speed with which the particle was projected.

Q2. Find the length OB along the inclined plane.

Q3. Find the speed at point B.
