Answer Details

The displacement-time graph represents the motion of an object thrown upwards. At point P, the object reaches its maximum height and then starts to fall back down due to gravity. At this point, the velocity of the object is zero, as it momentarily stops moving upwards and starts to fall downwards. Therefore, the correct answer is "zero".
