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 ..
