You will find two trajectories:
Blue particle will move in straight line and green particle will move along a circular path.
Assume there is no friction and under the same gravitation field.
Which one will arrive bottom earlier?
And can you explain it ? (The reason in phyisc!)

You might want to check show vx(t)!
