AI Thread Summary
To calculate the area under the graph in the shaded region, consider using trapezoidal estimation based on the grid provided in the image. Each square on the grid represents 0.16 Joules, so you can sum the areas of the complete squares and estimate the area of the partial squares. If you're unfamiliar with using a calculator for this purpose, guidance on basic operations can be provided. It's important to demonstrate some effort in understanding the process. Engaging with the material will lead to a better grasp of the concept.

Okay, so my question is: given the picture below, how can I find the area below the graph (in the shaded region) ? It's for a lab that I did in class, but it wasn't until i finished the whole picture that i realized that I didn't know how to calculate the area of this graph.

Thanks.

HINT: Think trapezoids! :)
 
If an estimate is good enough, just notice that each square represents 0.16*1 Nm = 0.16 Joules. Then just add up the squares and estimate for the non-complete squares.

at this point, i really need a definite answer ASAP, perhaps u can teach me how to use a calculator?

Perhaps I am reading this wrong!

You have been given some very sound advise in this thread already. Why don't you show us some effort on your part.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
