#4 The problem involves a track with three sections: A-B, B-C, and C-D. Here's a detailed breakdown:1. **Track Description:** - **Section A-B:** This is a quarter circle with a radius of 1.5 meters and is frictionless. - **Section B-C:** A horizontal span with friction; the coefficient of kinetic friction \( \mu_k \) is 0.3. The length of this span is 3 meters. - **Section C-D:** This section is frictionless and contains a spring.2. **Initial Conditions:** - A block with a mass of 1 kg is released from rest at point A.3. **Observation:** - The block compresses the spring by 0.15 meters after sliding on the track.4. **Tasks:** - Determine the following: - (a) The velocity of the block at point B. - (b) The work done by friction as the block slides from B to C. - (c) The velocity of the block at point C. - (d) The spring constant of the spring.5. **Diagram Description:** - The diagram shows the track starting at A, curving down to B (quarter circle, frictionless), then following a straight line from B to C (friction \( \mu_k = 0.3 \)), and finally reaching D where the spring is located.This problem requires understanding concepts of energy conservation, frictional work, kinematics, and spring compression to solve the given tasks.

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

The problem involves a track with three sections: A-B, B-C, and C-D. Here's a detailed breakdown:

1. **Track Description:**
- **Section A-B:** This is a quarter circle with a radius of 1.5 meters and is frictionless.
- **Section B-C:** A horizontal span with friction; the coefficient of kinetic friction \( \mu_k \) is 0.3. The length of this span is 3 meters.
- **Section C-D:** This section is frictionless and contains a spring.

2. **Initial Conditions:**
- A block with a mass of 1 kg is released from rest at point A.

3. **Observation:**
- The block compresses the spring by 0.15 meters after sliding on the track.

4. **Tasks:**
- Determine the following:
- (a) The velocity of the block at point B.
- (b) The work done by friction as the block slides from B to C.
- (c) The velocity of the block at point C.
- (d) The spring constant of the spring.

5. **Diagram Description:**
- The diagram shows the track starting at A, curving down to B (quarter circle, frictionless), then following a straight line from B to C (friction \( \mu_k = 0.3 \)), and finally reaching D where the spring is located.

This problem requires understanding concepts of energy conservation, frictional work, kinematics, and spring compression to solve the given tasks.
