a person needs to push a lever down with a force of 16.5N and a distance of 0.75 to lift the rock 0.25m. how much work is done?
To determine the work done, we can use the formula:
Work = Force × Distance
In this case, the force applied is 16.5 N and the distance over which the force is applied is 0.75 m. So, substituting these values into the formula, we get:
Work = 16.5 N × 0.75 m
Multiplying these values gives us:
Work = 12.375 N·m or 12.375 Joules
Therefore, the work done to lift the rock is 12.375 Joules.
