Paul wants to launch on a tiled soil, very smooth, a wet soap which slides on one of its faces. He thinks the soap is going to represent a rectilinear and uniform movement. Julie thinks the soap is going stop because of is weight.
1. What are the assumptions which Paul must consider to justify his assertion ?
2. Is Marie wrong ? Why ?
3. Actually, we notice the soap stop after a while.
a) What is the nature of the movement ?
b) What can you deduce ?
Good luck…
