A force F is exerted by a broom handle on the head of the broom, which is of mass m. The handle is at angle theda to the horizontal. (where it's tilted towards the left at about 30 degrees to the horizonal). The work is:
a)fdsin theda
b)fdcos theda

This would be b) right? Although the angle is a bit different that normal.

If the broom moves a distance d, and the force is applied in the direction of the broom handle, then the answer is (b)
