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 five 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) | 400 | 550 | 700 | 500 | 600 |
Distance (m) | 2 | 0.5 | 0.75 | 1.5 | 3 |
Use MATLAB to find (a) the work done on each segment of the path and (b) the total work done over the entire path.
