Work is the product of force and displacement. While the displacement is known to be at 1.5 meters, the force is not known. Force is a product of mass and acceleration. While mass is known to be 6kg, the amount of acceleration is not known. Because acceleration is not known, force cannot be found, thus the amount of work is also unknown.
88.2 J
Work = force x distance = 200 joules
Yes very very slightly.
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.
No

39.2 J
Work = force x distance = 200 joules
In general, garage lifts are used to lift cars. However, they can lift anything although not recommended. For example, it can lift a person or an ATV or a book.
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
Yes very very slightly.
You can paint shelf liner but it may not look so good if it starts to lift.
false

no, but the POTENTIAL energy may equal the work done to life the book to the shelf
These lifts are designed to lift a car with ease - they are machines and require a power supply and that varies by manufacturer. the main selling point of a car lift is that it can "double your space) in your garage by lifting you car up on something that looks like a bunk bed.
