------------------------------------------------ A 190 kg block is pulled at a constant speed of 4.1 m/s across a horizontal floor by an applied force of 128 N directed 22° above the horizontal.

What is the rate at which the force does work on the block?

Answer :

Final answer:

The rate at which the force does work on the block is zero.


Explanation:

The rate at which the force does work on the block can be calculated using the equation:

Work = Force x Distance x Cosine(angle)

Given that the applied force is 128 N and the block is pulled at a constant speed, the work done is zero because there is no change in kinetic energy. The angle above the horizontal (22°) is not relevant to the work done in this case.
