**bobpursley**, Sunday, May 27, 2012 at 6:55pmby you: 198*distance

by friction: 151*distance

by gravity: zilch

net force= force pushing-frictionforce

**Delbarre**, Sunday, May 27, 2012 at 7:05pmW=F.d , W= (198.0N)(3.6m)cos 0, W=712.8 N.m

this is your work.

W=(151.0N)(3.6)cos 180, W=(-1)543,6N.m

this work is negative because the force of friccion is opposite a the direction of movement y therefore the angle is 180

for last the total work is the sum of the all work

PS: the work of gravity is perpendicular

a the movement therefore cos 90 = 0.

Work gravity is 0

enjoy your answer.
