Expert Answer

Step 1

For the figure illustrated above, The Force F1 acts on the crate in the direction of the displacement of the crate.

The expression for work  W1 done on the crate due to force F1 is,

Step 2

Here d is the displacement of the crate.

Therefore the work W1 done on the crate is positive.

The Force F2  acts on the crate in the direction perpendicular of the displacement of the crate vertically downwards.

The expression for the work  W2 done on the crate due to force F2 is,

Step 3

Therefore, no work is done on the crate due to the force F2.

The Force F3  acts on the crate in the direction perpendicular of the displacement of the crate vertica...
