Hey guys, so I'm having some trouble, not sure if back of the book is wrong or if I'm doing it wrong, probably me though lol.
Alright so I have this graph,

So I know that displacement = area of a velocity- time graph,
therefore at first I assumed it was a trapezoid but that didn't make sense so I used area formulas separately and am getting,
1/2bh+bh+1/2bh
Using this formula I get 39 m/s2 East but in the back it shows as 36 m/s2 East.1/2(5)(6)+(3)(6)+1/2(2)(6)
