Combination W-K problem with spring

Finally, use the principle of conservation of momentum to find the final velocity of slider B. In summary, the conversation discusses the process of finding the velocity of slider B after an elastic collision with slider A, which has been released from rest against a compressed spring. The solution involves using formulas for energy and kinetic energy, calculating initial velocity, determining acceleration down the ramp, and applying the principle of conservation of momentum. The final velocity of slider B is determined to be 8.8.

Homework Statement



The 2 Kg slider A is held at rest against the spring k=900 compressing the spring by 0.4m. It is released and slides down the 5 m long ramp. Friction is negligible along the track. Slider A then makes an elsastic collision with the 3Kg slider B that is initially at rest. Find the velocity of slider B right after the collision.

Homework Equations

Start by using the formulas for energy stored in a spring and kinetic energy. Use these to calculate initial velocity. Then find out how much it accelerates down the ramp.
 

1. What is the Combination W-K problem with spring?

The Combination W-K problem with spring is a physics problem that involves a weight (W), a pulley system (K), and a spring (spring constant, k). It is used to understand the relationship between these three components and how they affect each other in a mechanical system. It is often used in introductory physics courses to demonstrate concepts such as force, equilibrium, and energy.

2. How do you solve the Combination W-K problem with spring?

To solve the Combination W-K problem with spring, you need to use the principles of static equilibrium and Hooke's law. First, draw a free-body diagram of the system and label all the forces acting on each component. Then, set up equations for the forces in the vertical and horizontal directions and solve for the unknown variables. Finally, use Hooke's law to determine the displacement of the spring.

3. What factors affect the behavior of the Combination W-K problem with spring?

The behavior of the Combination W-K problem with spring is affected by several factors, including the weight of the object, the spring constant, and the angle of the pulley system. Changing any of these variables will result in a different equilibrium position and displacement of the spring.

4. How does the Combination W-K problem with spring relate to real-world situations?

The Combination W-K problem with spring has many real-world applications, such as in engineering and construction. It can be used to design pulley systems and springs that can support a certain weight or to understand the forces acting on a structure. It is also used in the design of shock absorbers and other mechanical systems.

5. What are some common misconceptions about the Combination W-K problem with spring?

One common misconception about the Combination W-K problem with spring is that the weight of the object affects the spring constant. In reality, the spring constant is a property of the spring itself and is not affected by external factors. Another misconception is that the angle of the pulley system does not affect the equilibrium position. In fact, a larger angle will result in a larger displacement of the spring.
