How Far Do Dishes Move During a Tablecloth Trick?

[bhatch1]

Homework Statement

A magician pulls a tablecloth from under some dishes, how far do the dishes move during the.25s it takes the table cloth out? Coefficient of kinetic friction=0.12 and time=.25s I can't find the solution to this prob. in fact I don't know where to start because I don't have mass or weight.

Try drawing a free body diagram of the forces acting on the dishes. By applying Newton's laws, you may find that you don't need to know the mass.

Thanks you I figured it out all I needed was acceleration, and then then I found the distance.
