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?
