Problems with velocity-time graphs

[DoctorJesus]

Homework Statement

There are many variables and many questions, I'd just like to know how to go about it because I can't seem to understand the teacher and he's always in the way when he writes down equations, also he's a bit sporadic when it comes to giving us notes, jumping from subject to subject.




- Need formula for displacement on a velocity-time graphs and where (and how) i find the variables

- Need formula for instantaneous velocity from a velocity-time graph and where (and how) i find the variables

- Need formula for acceleration from a velocity-time graph and where (and how) i find the variables


Last but not least

- Need formula for average velocity from a velocity-time graph and where (and how) i find the variables

Homework Equations

- This is what I'm trying to find

The Attempt at a Solution

I've read through my notes many times but they seem too sporadic and unorganized so i plan on re-doing the notes based on this post


thanks!

There was a similar problem in the forum a few days back:
