Given that the angular acceleration \(\ddot{\theta} = 0\) and the radial acceleration \(\dot{r} = 0\) in the polar frame, the task is to determine the necessary spring constant. It also requires determining the normal force at this instant. These should be expressed in terms of one or more of the following variables: \( (v, m, r, l_0, \theta) \).**Hint:** Begin by solving for \(\dot{r}\) and \(\dot{\theta}\) from the velocity kinematics.**Diagram Explanation:**- The diagram illustrates the slider \( P \) moving on a vertical shaft.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

The problem involves a slider, modeled as a particle \( P \) with mass \( m \), moving along a frictionless shaft in the horizontal plane, where there is no gravity. At the indicated instant, the slider's speed is \( v \), and the spring is stretched to a length \( r \), greater than its unstretched length \( l_0 \). The spring forms an angle \( \theta \) as shown, and the spring constant \( k \) is unknown. Given that the angular acceleration \(\ddot{\theta} = 0\) and the radial acceleration \(\dot{r} = 0\) in the polar frame, the task is to determine the necessary spring constant. It also requires determining the normal force at this instant. These should be expressed in terms of one or more of the following variables: \( (v, m, r, l_0, \theta) \).

**Hint:** Begin by solving for \(\dot{r}\) and \(\dot{\theta}\) from the velocity kinematics.

**Diagram Explanation:**

- The diagram illustrates the slider \( P \) moving on a vertical shaft. The slider, connected to a spring, moves in the horizontal plane.
- The spring extends to a distance \( r \) from a fixed point \( O \), forming an angle \( \theta \) relative to the horizontal axis.
- Motion is indicated by vectors: \( v \) for velocity of the slider and \( \theta \) marking the angular direction formed by the spring.
