Is the Elastic Collision Equation Applicable in This Mechanics Scenario?

AI Thread Summary
The discussion centers on the applicability of the elastic collision equation in a mechanics scenario involving two objects with specified masses and velocities. One participant questions whether the elastic collision equation is appropriate for the given parameters. Another participant humorously points out that humans do not bounce well, suggesting that the scenario may not fit the elastic collision model. The conversation shifts towards exploring other conservation laws relevant to the problem. Overall, the participants are evaluating the correct approach to solving the mechanics scenario.

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?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
