Hi friends, I am preparing for my exam and i am stuck with this problem, please help me out. It wont take too long, I hope. 1. The problem statement, all variables and given/known data Two bodies A and B have masses mA and mB respectively and collide completely inelastic. Given that the mass of body A is 1200 kg and body B is 800 kg determine the avergage force vectors acting on each body during the collision. The collision itself lasts for 0.2 s. 2. Relevant equations Velocity of body A: (5i + 3j) m/s Velocity of body B: (-i + 4j) m/s Common velocity after collision I found to be: (2.6i + 3.4j) m/s (this eq was derived in a previous question with mA = 3/2 mB) 3. The attempt at a solution Well, I have tried using the momentum impulse theorem only to find out that the total momentum was conserved, which is good indeed. However I dont know how to find the answer I have kind of like used up my knowledge on impulse. The answer is (-14400i + 2400j) N. I have no clue how this answer was derived. Please help.
