A car (m=2000 kg) travelling at 20 m/s hits a deer (m=300 kg) standing still in the middle of the road. If the driver does not hit his brakes and the deer land on the hood of the car and stays on the hood, how fast does the car/deer object travel (v1) after the collision? PART 2: What is the momentum of the car (pc) and the deer (pd) before the collision, and the momentum of both (pb) after the collision? Please, i really need help! Thank you!! :D
Answer:
Part 1 and Part 2 can be answered at the same time using the conservation of momentum. pi=pf pc+pd=pb...

I get that the formulas are simple and easy to understand. Even with collision. I just don't really get Impulse and Momentum itself. For example,a problem given to us: a 0.1kg ball initially at rest is acted upon by a force of 4N for 2. Find the Impulse...
