Determine the Instantaneous Velocity of two coordinates on a graph

jmedina94

I can't provide all the information, because I'm on my mobile phone. Here is a shot of the problem:

The tangent of each curve is the slope, right? So how do we use that to find vf (instantaneous velocity) at 4s and 8s

hi jmedina94!
yes, the tangent is the slope

and the slope is the velocity …

so just count squares

Right! Duh! Is there a way to delete this post XD

tiny-tim

nope!

but it may help some other people too

True. Thank you!
