Found the speed change of the bin by Conservation of momentum. Then divide the speed change by 0.400 seconds.
But why momentum will stay the same?? I'm so confused about this point😭🤯
Prove that by Newton 2nd law. The force is equal to the reaction force. F=mass of car(Hereinafter referred to as m1) multiply acceleration of car The acceleration is equal to the velocity of the car (Hereinafter referred to as v1) divide by time. So give the formula that m1 multiply v1 is equal to m2 multiply v2. It's why the momentum always stay the same.
I see... Do u mind if I wanna ask you another question? It's about impulse.
Fine. I am honored to help you. In fact, I can speak Chinese. 😂😂
I know u can lolll but I thought u wanna use English🤣
I use English just for the question which is in English. 好啦回到中文哈哈哈 我英文其實滿爛的👍 有問題可以再問!
