What is the Work Done by Various Forces on a Bucket Moving with a Broom Stick?

[alexparker]

A Child uses a broom stick to push a 2.0kg bucket of water across a floor. The Broom Stick is held at an angle of 60 degrees to the horizontal and exerts a force of 100N on the bucket. The bucket is initially at rest and encounters a constant frictional force of 10N while moving a distance of 5.0m. Assume the g is 9.8m/s/s, and that the effects of air resistance are negligible.

For the 5.om distance, calculate the work done by:
A) the horizontal component of the 100N Force

B) The frictional Force

C) The Resultant horizontal Force

Have you tried drawing a free body diagram of the forces involved and finding the net horizontal force?

Use W=F\cdot d to calculate the work.
