- 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 top-view 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
