Vamsi and Gravity

CodeChefOpen on judge ↗

One day Vamsi was on his roof. He dropped a ball with no initial velocity. He is observing the direction in which ball is moving. You have to tell the direction of ball either "Up" or "Down" at a time T after start of the event. If ball is touching ground write "Bottom" or if ball is at the maximum height(Velocity=0) write "Top". Consider Gravity=10m/s2 and all collisions to be perfectly elastic
