I see you're in Middle School, so I've got a hunch that they want you
to say "the dresser because it has more mass". But that's a poor
answer, to a poor question.
The fact is that there's no way to tell.
The force it takes to move either object across the floor does NOT really
depend on just its mass. It depends on both the object's mass AND the
friction between the object and the floor. And THAT depends on the shape
of the feet where they touch the floor, and what kind of material the feet and
the floor are made of.
So it seems to me that we really don't have enough information to answer
the question with.
But again, I suspect that the answer they want is "the dresser because
it has more mass".
80 (km / hour) * (1,000 meters/ km) * (1 hour/ 60 minutes) * (1 minute / 60 seconds) = 22.2 meters / second

The law of conservation of energy states that the energy cannot be created or destroyed, either it is transferred from one object to another.
Explanation:
The principle of conservation of energy is the energy is not created or destroyed it is only moved from one place to another.
There are various examples to explain the conservation of energy. some of them are explained here.
- If the moving car hits the parking car and that makes the parked car to move, at this state the energy is transferred from the moving car to the parked car.
- If you are pushing a book across the table, then the energy from your moving arm is transferred from your body to the book and that causes book to move.
- The another example for conservation of energy is A dog is running towards the tree and it gets hit to it. In this case the energy is transferred from moving dog to the tree, and causes the tree to move.
