Question

When less force is used but the amount of work done remains the same, how does distance change?

Answer 1

Lee has been moving a crate that has a mass of 125 kg and required 120 J of work to move. The crate was moved a distance of 20 meters in 30 seconds. What was the power output?

Answer 2

You know that W=Fd, and you know that P=W/t, so if you know the work done, and the time it took, you can calculate the power.

Answer 3

Ok thanks

Answer 4

Work = Force times distance

So if force decreases, distance must increase for work done to stay the same.
