Question

For the position-time graph attached inside, what is the average velocity for the entire curve?

A. -10 m/s

B. -4 m/s

C. +4 m/s

D. +10 m/s

@zepdrix do you get this one? Another graph problem :/

Answer 1

graph!

Answer 2

What do you think?
I think you could eliminate two choices already

Answer 3

it would have to be negative right? since it's moving at a downward slope? So C and D are out?

Answer 4

Yes.
And to find velocity and think you could just find the slope of the line using the first and last point

Answer 5

ohh okay... so you end up getting 100/25=4 ? so the answer is B. -4 m/s ?

Answer 6

@nikato ?

Answer 7

Yes. That is what I would put

Answer 8

yay, thanks!! :)

Answer 9

No problem
