Transcribed Image Text:**Problem 2:**
A 2.0 kg particle moving along the x-axis experiences the force shown below, which changes as the position \( x \) of the particle changes. The particle’s velocity is 4.0 m/s at \( x = 0 \, \text{m} \). Use the work-kinetic energy theorem to answer the questions below.
(a) What is the particle’s velocity at \( x = 2 \, \text{m} \)?
(b) What is the particle’s velocity at \( x = 4 \, \text{m} \)?
**Graph Explanation:**
The graph depicts the force \( F_x \) (in Newtons) experienced by the particle as a function of its position \( x \) (in meters).
- The force starts at 10 N when \( x = 0 \).
- The force decreases linearly, reaching 0 N at \( x = 2 \).
- The force continues to decrease, reaching -10 N at \( x = 4 \).
The work done by this force on the particle is the area under the force-position graph.
