I have no idea how to answer these questions. Please help.
Conclusion:
1. Use the data collected to develop an equation (claim) that expresses the post-collision velocity as a function of the masses and their motion pre-collision. Support your claim with evidence from your data using specific references to trials included in your data table. Explain your reasoning as to how and why the data supports your claim.

2. Study the momentum values pre-collision and post-collision. Can you identify any trend(s) in the data? Support your claim with evidence from your data using specific references to trials included in your data table. Explain your reasoning as to how and why the data supports your claim.

I'm sorry but I can't help in physics; however, I CAN comment on why you aren't getting any help. You post a question about conclusions from data as well as momentum. You don't have any data, at least you didn't post any. Are we supposed to make up data to fit a fictional problem. If you don't post the data how can ANYONE draw conclusions or give supporting evidence about momentum. momentum, by the way, is mv. I expect you can get some help if you post a question that make sense and that has all of the supporting materials with it.
Ok "Bob", id I had the "data" that you need then I would obviously post it with the question. My teacher only sent me these two questions with no info about the data or what's it based on. I already emailed my teacher and they said to just answer it. And I did post a question that make sense and that has all of the supporting materials with it which is a few questions before this one. So either please check it out or don't even answer with your rude attitude.
To answer these questions, you will need to analyze the data you collected during your experiment. Here's a step-by-step guide on how to approach each question.
Question 1: Developing an equation (claim) for post-collision velocity
1. Review your data table: Look at the trials you conducted and collected data for. These trials should include information on the masses and the motion of the objects before and after the collision.
2. Identify patterns: Look for any consistent relationships between the masses, motion, and post-collision velocities. Pay attention to any direct or inverse relationships that may exist.
3. Develop an equation: Based on the patterns you identified, formulate an equation that expresses the post-collision velocity as a function of the masses and their motion pre-collision. For example, if you noticed that post-collision velocity is directly proportional to mass and the initial velocity of one object, you might come up with an equation like: post-collision velocity = (mass A * initial velocity A) / mass B.
4. Evidence & Reasoning: Provide specific references to the trials included in your data table to support your claim. For example, you can reference Trial 1, where object A had a mass of 2 kg, an initial velocity of 5 m/s, and object B had a mass of 3 kg. Calculate the post-collision velocity using your equation and compare it to the observed velocity from trial 1. Explain how your equation accurately predicts the observed result based on the relationships you identified.
Question 2: Identifying trends in momentum values
1. Examine the momentum data: Look at the momentum values before and after the collision in each trial. Calculate the momentum using the formula momentum = mass * velocity.
2. Identify trends: Compare the momentum values before and after the collision for each trial. Look for any consistent patterns or changes in momentum. Pay attention to whether momentum is conserved or if there are any deviations from conservation.
3. Formulate a claim: Based on the observed data, make a claim about the trend(s) in the momentum values. For example, if you noticed that the sum of the momentum before the collision was equal to the sum of the momentum after the collision in each trial, your claim may be: "Momentum is conserved in all collision scenarios."
4. Evidence & Reasoning: Support your claim with specific references to trials included in your data table. For example, reference Trial 2, where the total momentum before the collision was 10 kg·m/s, and the total momentum after the collision was also 10 kg·m/s. Explain how these specific values demonstrate the conservation of momentum and provide additional reasoning based on other trials to further support your claim.
By following these steps, you can provide comprehensive and well-supported answers to the questions. Remember to refer back to the specific data in your data table and use mathematical formulas and reasoning to guide your responses.
Two comments:
1. I'm sorry the profs were not very cooperative and not helpful in providing the data.
2. Telling it like it is is not being rude. It's being informative. You should have known that with no data an answer to your post was impossible. I simply answered your question as to why you weren't getting a response. Good luck in your class(es) and in your future.
