<u>Answer:</u>
For this situation the right answer is d, <u>the kinetic friction</u>, because in this case we are talking about moving surfaces: the surface of the box moving along the surface of the floor.
When this happens <u>there may be a force that acts in </u><em><u>opposite direction</u></em><u> to the movement of the box and tends to stop it (Friction)</u>.
The other options are <u>not correct</u> because:
a) The cohesive friction does not exist
b) <u>The Rolling Friction</u> applies for a body that rolls on a surface (an object with the shape of a circumference for example), and in this case the situation described is with a box
c) <u>Static Friction</u> is the friction in a body that keeps at rest. <u>In this situation is not applied because </u><em><u>the body is in motion</u></em><u>
</u>
d) Potencial friction does not exist
