Default Physics Question:?

A particle, starting from point 'A' is projected down a curved diagonal runway. (point A is located at the top of the runway). The runway then curves upwards at the bottom (causing the particle to fly straight up (verticle) - Point 'B'. When the particle is launched off part B, it reaches a height of 4.00m above the floor before falling back down. Ignoring friction and air resistance , find the speed of the particle at point A.

Note: Point A is located 3m off the floor.
