**Problem Statement:**A particle of mass \(4.0 \, \text{kg}\) moves under the influence of the force \( F(x) = (-5x^2 + 7x) \, \text{N} \). If its speed at \( x = -2.4 \, \text{m} \) is \( v = 24.0 \, \text{m/s} \), what is its speed (in m/s) at \( x = 2.4 \, \text{m} \)?**Answer Box:**\[ \boxed{} \text{ m/s} \]**Explanation:**This problem involves applying the work-energy principle to find the change in kinetic energy resulting from the work done by a variable force. The force \( F(x) = (-5x^2 + 7x) \, \text{N} \) implies a varying interaction between the force and displacement along the x-axis. The task is to calculate the final speed of the particle given its initial speed at a specific position.
