Is the Elastic Collision Equation Applicable in This Mechanics Scenario?

Click For Summary
SUMMARY

The discussion centers on the applicability of the elastic collision equation in a mechanics scenario involving two objects with specified masses and velocities. The participants clarify that the elastic collision equation is not suitable for this situation, as it does not account for real-world factors such as energy loss during collisions. Instead, they suggest considering other conservation laws, such as momentum conservation, to analyze the problem effectively.

PREREQUISITES
  • Understanding of elastic and inelastic collisions
  • Familiarity with conservation of momentum
  • Basic knowledge of physics equations related to motion
  • Ability to perform calculations involving mass and velocity
NEXT STEPS
  • Study the principles of momentum conservation in collisions
  • Learn about inelastic collision equations and their applications
  • Explore real-world examples of collisions and energy loss
  • Investigate the differences between elastic and inelastic collisions in mechanics
USEFUL FOR

Physics students, educators, and anyone interested in understanding collision dynamics and the application of conservation laws in mechanics.

Homework Statement
Can someone please help me solve this mechanics physics problem? Thank you
Relevant Equations
2. A 500 kg automobile travelling at 30 m/s strikes a 100kg stationary pedestrian. The impact duration is 0.1 s and it slows the automobile by 1m/s.

Calculate:
a. the velocity imparted to the pedestrian
b. the force exerted by the vehicle on the pedestrian.
So, I understand that there are 2 objects, so is the equation we are supposed to use is the elastic collision equation, right? I just need help getting started, thank you.

Certainly not. Humans do not bounce well.
What other conservation laws do you know?
