Kwame and Priya are standing on opposite ends of a rectangular rug. Kwame pulls the rug towards himself to show Priya a design on his end. Assuming Priya stands still, what happens to Priya as Kwame pulls the rug? Respond very briefly.
Priya will move toward Kwame because pulling the rug in one direction will create motion between the rug and the floor, but the friction between Priya's feet and the rug will cause her to move along with the rug in the direction Kwame is pulling it. The interaction between the rug and Priya is relative to the force exerted by Kwame on the rug and the friction between her feet and the rug's surface; if the friction is less than the force with which Kwame pulls the rug, Priya might slip somewhat but still move in Kwame's direction. If the friction is strong enough, she will move smoothly with the rug without slipping.
