In the second part of this question, I am supposed to find the turning part of the particle. What does the turning point mean in this situation and how do I go about solving this question? I have a screenshot of problem included.

Step 1

For x = 1.0 m,

The potential energy is 20 J

And, from the graph

Fx = - 20 N

Speed of the particle, v = 21 m/s

Step 2

Total energy at x = 1.0 m:

E K.E+ P.E
