Question

physics

Answer 1

I already did my work for the entire problem, If you could check it

Answer 2

"The student doesn't accelerate the elevator does" is wrong.

The student is standing on the elevator, so his velocity and the elevator's velocity have to be the same at all times. The elevator is accelerating, so its velocity is changing, and so is the student's velocity. The student is accelerating as well.

Answer 3

therefore the \(F_{net}\) on the man is not 0 whenever the elevator is accelerating

Answer 4

"Reading of scale is minimum when \(-|a|\) is the greatest" need some correction as well.

Answer 5

what if your graph was like this-


- |a| is greater when a is 100.

when you take the mod, you essentially remove the "direction." So saying that" -|a| is greatest is the negative direction " is vague because -|a| has no direction.
Also, what if the acceleration was never negative? That case, too, can have a minimum scale reading, which would be at a=0. We need to fix a few things here

Instead of using -|a| use a. And then you could say that the scale would have the minimum value for the least possible a.

Answer 6

@Luvz17 make a new post for your question :-)

Answer 7

good helps muscle

Answer 8

True dat for the - |a|, I just didn't know how to word it at the time lol. A better idea would have been just saying where a is the least possible value and I wouldn't have had to write all that.

And thank you for
"The student is standing on the elevator, so his velocity and the elevator's velocity have to be the same at all times. The elevator is accelerating, so its velocity is changing, and so is the student's velocity. The student is accelerating as well."
I should have realized that when you are in something, you have the same movement as it. Like if your in a car that accelerates than you accelerate as well.

Thank you :)
