Question

For a machine, the input force is 30 N, and the input distance is 2 m. Factoring in the effect of friction, what must be true about the work output? Group of answer choices It must be less than 60 J. It equals 60 J. It must be greater than 60 J. Not saved

Answer 1

60J

Step-by-step explanation:

To determine the work output, we need to consider the effect of friction. Friction can reduce the efficiency of a machine and result in a lower work output compared to the ideal case.

Work is defined as the product of force and displacement:

Work = Force × Distance

In this case, the input force is 30 N and the input distance is 2 m, so the input work would be:

Input Work = 30 N × 2 m = 60 J

If we factor in the effect of friction, the actual work output may be less than the input work. Therefore, in this context, the work output must be less than 60 J. So the correct answer is: It must be less than 60 J.
