can someone help i'm stuck on two questions???
23. On a velocity-time graph, when is the object not moving?
when the slope is a straight line rising to the right
when the slope is a straight line falling to the right
when the slope is a line curving upward to the right
at the point in which the line crosses the x-axis
27. How do you find the instantaneous velocity on a position-time graph?
Find the slope of the tangent at any point.
Find the slope of the overall trend line.
Find the slope between any two points.<---- i think this one
Find the slope of only horizontal portions.<---- or this one
is anyone going to help????? im clueless :(
nvm i found them out and i really am disturbed that no one wants to help out
We are volunteers, Mary Ann. I find it troubling that you think volunteers will be waiting for you to post.
i don't think , i just asked because i seen you helping out people very quickly but when i posted my Q, u didn't help out at all. also my time was limited on the quiz
So ... you were cheating while taking a quiz?
???
=(
"i don't think"
Sure, I'd be happy to help you with these questions!
23. On a velocity-time graph, when is the object not moving?
To determine when the object is not moving on a velocity-time graph, we need to look at the slope of the line. The slope represents the rate of change of velocity over time. When the slope is a straight line falling to the right (negative slope), it indicates that the object is moving in the negative direction or decelerating. Therefore, the correct answer is: when the slope is a straight line falling to the right.
27. How do you find the instantaneous velocity on a position-time graph?
To find the instantaneous velocity on a position-time graph, we need to find the slope of the tangent line at a specific point. Instantaneous velocity represents the velocity of an object at a precise moment in time. By drawing a tangent line at that point and finding its slope, we can determine the object's instantaneous velocity. Therefore, the correct answer is: Find the slope of the tangent at any point.
I hope this helps! Let me know if you have any further questions.
