(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the particles Velocity at 7 seconds . ( Graph Below)

2. Relevant equations

3. The attempt at a solution

T=5 from 7-2

or

T=2 From 7-5 ( Because It's now -a)

I tried int from 0 to 5 -10dt and got -50

then AT=v with both

A @ 7 second = (-20*2)/2 = -20

Is velocity not negative.

I am really embarrassed to ask for help. I would love to understand , and maybe remind me some how science is fun ..
