Given:
The mass of the bucket is m = 35 kg
The bucket is lifted with a constant velocity of 1.87 m/s
The displacement of the bucket is d = 28.4 m
Required: Work done upon the bucket.
Explanation:
As the velocity of the bucket is constant, its acceleration will be zero.
So, the force on the bucket will be
[tex]\begin{gathered} F=m\times a \\ =35\times0 \\ =0\text{ N} \end{gathered}[/tex]The work done can be calculated as
[tex]\begin{gathered} W\text{ = Fd} \\ =0\times28.4\text{ } \\ =\text{ 0 J} \end{gathered}[/tex]Final Answer: The work done upon the bucket is zero.
