You can tell school's back in session. There's SO many questions that sound like they've been copied verbatim from an assignment or take-home test.
Open the text book, read the material, and apply it. In the long run, you'll be way better off.

Force of gravity is = m(ag) = 800kg(9.8m/s^2) = 7840kgm/s^2 = 7840N
8200N - 7840N = 360N
a = F/m = 360N / 800kg = 0.45m/s^2
And to the other 3 answerers. Get back to work! I'm going to be on my way in a couple of hours, so those quarter pounders with cheese better be ready when I get there!!!

F=ma
sum of forces=acelleration
8200-800=7400
