Want this question answered?
Work Done= Force applied x distance moved in direction of the force. so the work done should in this case be 40J
If the 25N force is directed straight up, so that the force itself moves 1.5 meters tofinish the job, then it does 37.5 joules of work, which becomes 37.5 more joules ofgravitational potential energy that the plant has, once it's on the shelf.
88.2 J
Work = force x distance = 200 joules
Yes very very slightly.
Yes you do because W = F . d meaning if you are applying a force to something over a distance then you are doing work on it
The potential energy of the book on the shelf is equal to the work done to lift the book to the shelf. This is because the potential energy of an object at a certain height is equivalent to the work done against gravity to lift it to that height.
no
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
false
zach is amazing

you have to put the lift on any floor then put another lift directly above the 1st one. If you want to skip a floor put the lift shaft in between the 2 lifts on the floor you want it never to stop on.

you can take apart the shelf and move it or lift it up and put something underneath with wheels to role across
Work = force x distance = 200 joules
