When looking at the physics behind the spinning of clothes in a washer, i know that the clothes are separated from the water and thus the water is not separated from the clothes. But WHY? I need a good explanation, possibly relating to centripetal acceleration or uniform circular motion. (I know that other answers were since the clothes are heavier, they are separated first, but this is not an accurate explanation as determined by my teacher). Thanks for your time.

Consider a FBD of the clothes and FBD of a molecule of water. As the two spin, the force acted on each is
F=m*v^2/R, which forces the two away at equal acceleration until the clothes encounter the surface of the drum, now another force is introduced which balances the centripetal force on the clothes, but the water molecule happily continues through a hole in the drum. Viola, the clothes are separated from the water.

a = v^2/r You know the speed v because you know how far it goes (one circumference) in a given time (410 sec).
