I agree.toesockshoe said:how do you know that the final velocities of both masses are equal to each other? wouldn't that ONLY be hte case if the collision was perfectly inelastic (which he didnt mention).
alright, and in this case it would be simply impossible for the masses to have the same velocity... because the first mass (the mass on the left) would move left after the collision correct?haruspex said:I agree.
nevermind scratch that... that would only happen if it is an elastic collision... this may or may not happen in an inelastic collisiontoesockshoe said:alright, and in this case it would be simply impossible for the masses to have the same velocity... because the first mass (the mass on the left) would move left after the collision correct?
There are a few ways to check if your teacher's work for a collisions problem is correct. First, you can compare your teacher's solution to the solution provided in the textbook or class notes. Second, you can ask your teacher to walk you through their thought process and calculations to ensure they followed the correct steps. Third, you can try solving the problem yourself and compare your solution to your teacher's.
If you believe your teacher's work for a collisions problem is incorrect, you should first ask them to double-check their calculations and explain their reasoning. If you still believe there is an error, you can seek help from a classmate or a tutor. It is also important to bring up your concerns to your teacher so they can address any mistakes and help clarify any confusion.
Yes, there are often multiple methods for solving a collisions problem. Your teacher may have taught you a specific method, but you can always use a different approach as long as it is mathematically sound and leads to the correct answer.
Yes, there are a few common mistakes that students make when solving collisions problems. These include forgetting to account for all the forces involved, using incorrect units, and not properly setting up the equations of motion. It is important to double-check your work and make sure your calculations make sense in the context of the problem.
To improve your understanding of collisions problems, it is important to practice solving various types of problems and to seek help from your teacher or classmates when needed. You can also review class notes and textbook examples, as well as watch online tutorials or attend review sessions. Additionally, developing a strong understanding of the underlying principles and equations involved in collisions can also help you better solve these types of problems.
