- 12. There are two cars a and B on the smooth horizontal plane There are two cars a and B on the smooth horizontal plane, and there is a light spring in the middle. Hold the car by hand and compress the spring to make the car in a static state. Take the two cars and the spring as a system. The following statement is correct: there are two cars a and B on the smooth horizontal plane, and there is a light spring in the middle, Hold the car by hand and compress the spring to make the car in a static state. Consider the two cars and the spring as a system? A after releasing the two hands, the total momentum of the system is moderate to zero B put the left hand first and then the right hand. Momentum is not conserved C put left hand first, then right hand, total momentum left D no matter when the two hands are released, the total momentum of the system will remain unchanged in the process of the spring returning to its original length, but the total momentum of the system may not be zero
- 13. If two objects M1 and M2 connected by light springs are placed on a smooth plane, the masses are not equal. If force F pushes M1, will the springs be compressed? M1 = = = = M2 use constant force F to push M1 to the left. Because the plane is smooth, M2 is not subject to friction and can't give the spring a left force, so the spring can't be compressed. At this time, they can be regarded as a whole. Is it true that the spring won't be compressed? If one side of a spring is fixed on the wall, the other end of the push will be compressed, Because the wall gives it a force. And the above problem is smooth, is it not compressed?

The answer is - 1 / 2mV ^ 2 = - MGH + W, but I want to use - 1 / 2mV ^ 2 = - mgh-w bullet. In the question, w bullet does negative work, so it's listed. If I move the term to find w, I will get a different formula from the answer (just opposite to each other). Where's my question?
