[Bones]

Homework Statement

In the figure below,

http://www.webassign.net/userimages/jshemwell@lincolnpark.il/Net%20Force/Two_opposing_horizontal.gif

T1 = 32 N, and T2 = 19 N. The surface has no friction. The block travels a displacement of 11 m to the right as a result of these forces.
a. What is the work done on the block by T1?

b. What is the work done on the block by T2?

c. What is the work done on the block by gravity?

d. What is the work done on the block by the normal force?

e. What is the net work done on the block by all forces?

Homework Equations

The Attempt at a Solution

I got (32N)(11m)(Cos0)=325 J for a.
I got (19N)(11m)(Cos180)=-290 J for b.
I got 0 for c. and d.
I am not sure how to find e. and did I do the rest of the problems correctly?
