A particle, starting from point A in the drawing (the height at A is 3.00 m), is projected down the curved runway. Upon leaving the runway at point B, the particle is traveling straight upward and reaches a height of 6.39 above the floor before falling back down. Ignoring friction and air resistance, find the speed of the particle at point A.
