SUMMARY

The discussion focuses on solving the Combination W-K problem involving a 2 Kg slider A and a 3 Kg slider B. Slider A is initially held against a spring with a spring constant of 900 N/m, compressed by 0.4 m. Upon release, slider A slides down a 5 m ramp, undergoing an elastic collision with slider B, which is initially at rest. The final velocity of slider B after the collision is calculated to be 8.8 m/s using the work-energy principle and elastic collision equations.

PREREQUISITES
  • Understanding of the work-energy principle
  • Knowledge of elastic collision equations
  • Familiarity with spring mechanics and energy storage
  • Basic principles of kinematics
NEXT STEPS
  • Study the work-energy theorem in detail
  • Learn about elastic and inelastic collision formulas
  • Explore the concept of energy stored in springs
  • Investigate kinematic equations for motion on inclined planes
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators looking for practical examples of energy conservation and collision dynamics.

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



I used w-k equation then elastic collision to find V'B

The Attempt at a Solution



The answer suppose to be 8.8

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.
