### Topic: Spring-Block System#### Problem Statement2. (Ch. VII, Exercise 8) A block of mass \( m \) is attached to a spring with a spring constant \( k \), and is pulled a distance \( A \) from that point at which the spring is unstretched (\( x = 0 \)).**Questions:**a. If there is no friction, how far will the block go if it is released from rest?b. If there is a non-zero coefficient of friction between the block and the surface, find \( x_s \), the point at which the block will stop if released from rest.#### Explanation of Diagram:The diagram illustrates a horizontal spring-block system with the following components:- A spring with constant \( k \), attached to a block of mass \( m \).- The block is initially displaced to the right to a position \( x = A \) from the equilibrium position \( x = 0 \).- The positive \( x \)-direction is indicated to the right.In the absence of friction, once the block is released, it will exhibit simple harmonic motion. When friction is considered, the block will eventually come to a stop due to the resistive force. The position \( x_s \) will be determined by the balance between the restoring force of the spring and the frictional force.### Solutions:**a. No Friction:**When there is no friction, the block will continue oscillating indefinitely between \( -A \) and \( A \) due to the conservation of mechanical energy in a frictionless system.**b. Non-Zero Coefficient of Friction:**In the presence of friction, the block will lose energy due to the frictional force, which results in the gradual reduction of the amplitude of oscillations until it comes to rest. To find \( x_s \), we would use the work-energy principle, considering the energy lost due to friction.The force of friction \( f \) can be calculated as:\[ f = \mu mg \]where \( \mu \) is the coefficient of friction and \( g \) is the acceleration due to gravity.The block will stop at \( x_s \) where the work done by the frictional force equals the potential energy stored in the spring:\[ \frac{1}{2} k x_s^2 = \mu mg x_s \]Solving for \( x_s \

Spring Potential Energy

The potential energy is the energy possessed by a body by virtue of its position or the energy held by the object due to its position relative to other objects, its force like stresses, charge, and other factors affecting the particles of the body. The potential energy is the measure of the net work done by or on the body. The spring potential energy is the potential energy stored due to the deformation of an elastic spring and this elasticity is due to the stretched spring. The elasticity is the ability of a solid-state matter to come back to its equilibrium position or original position after any kind of external force is acted on it. It is also known as Elastic potential energy. The potential energy here is caused due to the displacement of the spring from its equilibrium position to another position and this potential energy is equal to the net work done due to the stretching of the spring. It also resembles the same mechanics of the oscillation of a simple pendulum, where due to the external force, the object moves from its equilibrium position to its maximum ends and the periodic motion continues till it comes back to the equilibrium position to rest. 

Question

### Topic: Spring-Block System

#### Problem Statement

2. (Ch. VII, Exercise 8) A block of mass \( m \) is attached to a spring with a spring constant \( k \), and is pulled a distance \( A \) from that point at which the spring is unstretched (\( x = 0 \)).

**Questions:**
a. If there is no friction, how far will the block go if it is released from rest?

b. If there is a non-zero coefficient of friction between the block and the surface, find \( x_s \), the point at which the block will stop if released from rest.

#### Explanation of Diagram:

The diagram illustrates a horizontal spring-block system with the following components:
- A spring with constant \( k \), attached to a block of mass \( m \).
- The block is initially displaced to the right to a position \( x = A \) from the equilibrium position \( x = 0 \).
- The positive \( x \)-direction is indicated to the right.

In the absence of friction, once the block is released, it will exhibit simple harmonic motion.

When friction is considered, the block will eventually come to a stop due to the resistive force. The position \( x_s \) will be determined by the balance between the restoring force of the spring and the frictional force.

### Solutions:

**a. No Friction:**
When there is no friction, the block will continue oscillating indefinitely between \( -A \) and \( A \) due to the conservation of mechanical energy in a frictionless system.

**b. Non-Zero Coefficient of Friction:**
In the presence of friction, the block will lose energy due to the frictional force, which results in the gradual reduction of the amplitude of oscillations until it comes to rest. To find \( x_s \), we would use the work-energy principle, considering the energy lost due to friction.

The force of friction \( f \) can be calculated as:
\[ f = \mu mg \]
where \( \mu \) is the coefficient of friction and \( g \) is the acceleration due to gravity.

The block will stop at \( x_s \) where the work done by the frictional force equals the potential energy stored in the spring:
\[ \frac{1}{2} k x_s^2 = \mu mg x_s \]

Solving for \( x_s \
