For my question about the carton's speed must I do each step you laid out or just the last one? I got the wrong answer. Thanks for your help.
I wish you had checked it step by step, and you would have immediately realized I mixed up the Sin, Cos terms, they are in opposite to what I typed.
Force down plane mgSinTheta, force friction mu*mg*CosTheta.
Duh on me, and duh on you for not working it through and checking.
I worked it through and checked it didn't make sense to me. But I have to finish the assignment soon so I put the answer in anyway. Thanks for you patience.
To clarify, if you are referring to the steps I provided for calculating the carton's speed, it is important to follow each step in order to obtain the correct answer.
Here's a recap of the steps that need to be followed:
1. Identify the given information: Make sure you have all the necessary details, such as the distance the carton traveled and the time it took.
2. Convert units if necessary: Check if any unit conversions are required. For example, if the distance is given in kilometers but you need it in meters, convert accordingly.
3. Use the formula: The formula to calculate speed is distance divided by time.
4. Substitute the values: Plug in the converted values into the formula. Make sure to double-check that the units match.
5. Perform the calculation: Divide the distance by the time to find the speed.
By following all these steps, you should be able to obtain the correct answer. If you only performed the last step and received an incorrect answer, it's possible that an error occurred in one of the previous steps or during the calculation itself.
If you encountered any specific difficulties or made any assumptions during the process, please provide more information so that I can assist you more effectively.
