Question: The mechanical work W done in using a force F to push a block through a distance D is W ! FD. The following table

The mechanical work W done in using a force F to push a block through a distance D is W ! FD. The following table gives data on the amount of force used to push a block through the given distance over ve segments of a certain path. The force varies because of the differing friction properties of the surface.

Path segment 1 2 3 4 5 Force (N) Distance (m) 3 400 550 700 500 600 0.5 0.75 1.5 5

Use MATLAB to nd

(a) The work done on each segment of the path and

(b) The total work done over the entire path.

Path segment 1 2 3 4 5 Force (N) Distance (m) 3 400 550 700 500 600 0.5 0.75 1.5 5
