**Problem Description**

A net force along the \(x\)-axis with an \(x\)-component given by the equation \( F_x = -12.0 \, \text{N} + (0.300 \, \text{N/m}^2)x^2 \) is applied to a 5.00 kg object. This object is initially at the origin and is moving in the \(-x\)-direction with a speed of 7.70 m/s.

**Question (Part A)**

What is the speed of the object when it reaches the point \( x = 7.70 \, \text{m} \)?

**Instructions**

Express your answer with the appropriate units.

**Student Response**

The student entered a velocity \( v = 8.78 \, \text{m/s} \).

**Feedback**

- The answer was marked as incorrect.
- The message indicated: "Incorrect; Try Again; 9 attempts remaining."

**Note**

- Ensure to apply principles of physics, such as work-energy theorem or kinematics equations, to solve for the speed at the specified position.
- Double-check calculations and consider the force's effect over the distance traveled.
