# If a worker pulls a 10kg bucket up a 25 m well, how much work has he or she done?

Hence, in the given case work done is

The work done by the worker is equal to the force applied multiplied by the distance moved in the direction of the force. In this case, the force is equal to the weight of the bucket, which is ( F = m \times g ), where ( m = 10 ) kg is the mass of the bucket and ( g = 9.8 ) m/s² is the acceleration due to gravity. So, ( F = 10 \times 9.8 = 98 ) N. The distance moved is ( d = 25 ) m. Therefore, the work done is ( W = F \times d = 98 \times 25 = 2450 ) joules.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- An object, previously at rest, slides #5 m# down a ramp, with an incline of #(3pi)/8 #, and then slides horizontally on the floor for another #16 m#. If the ramp and floor are made of the same material, what is the material's kinetic friction coefficient?
- A box with an initial speed of #2 m/s# is moving up a ramp. The ramp has a kinetic friction coefficient of #1/2 # and an incline of #(2 pi )/3 #. How far along the ramp will the box go?
- If a #10kg# object moving at #12# #ms^-1# slows down to a halt after moving #7 m#, what is the friction coefficient of the surface that the object was moving over?
- Three men are pulling on ropes attached to a tree the ﬁrst man exerts a force of 6.0 N north, the second a force of 35 N east, and the third 40 N to south. What is the magnitude of the resultant force on the tree?
