 Homework Statement:

On the tables, we located two points, P1 and P2. A particle moves from P1 to P2 without acceleration along five different paths. The duration is the same for all paths. If we put a point X, the suitable path with the lowest kinetic energy is
a. A
b. B
c. C
d. D
e. E
 Relevant Equations:
 Not sure
I am not sure I understand the question. I imagine there is a horizontal table and all the diagrams are the topview of the table.
The question states that "A particle moves from P1 to P2 without acceleration along five different paths". In the first picture, I think the path is in the shape of oval and the particle does not pass through point P1. And I also don't understand how can the particle moves in the path given by picture (a), (b), (c) and (d) without acceleration (constant velocity)
At first I thought the answer will be (c) because I imagine it moves just like in simple harmonic motion and point X is at its amplitude so zero velocity but considering "without acceleration", I do not know anymore.
Thanks
