The discussion centers on calculating the distance dishes move when a magician pulls a tablecloth from under them in 0.25 seconds, given a coefficient of kinetic friction of 0.12. Participants emphasize the importance of applying Newton's laws and suggest that mass is not necessary for the solution. By determining the acceleration of the dishes, users can compute the distance traveled during the time interval. The final solution involves using basic physics principles to arrive at the answer.
PREREQUISITESStudents studying physics, educators teaching mechanics, and anyone interested in understanding the principles of motion and friction in practical applications.
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.bhatch1 said: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.
