Friction and Pully

  1. Nov 8, 2007 #1
    An 8.0-kg hanging block is connected by a string over a pulley to a 6.5-kg block sliding on a flat table. If the coefficient of sliding friction is 0.28, find the tension in the string.

    is the answer 41.02 N ?

    How did you work it out?

    so, we assume that the 6.5 block is sliding? not at rest?

    i guess so

    well, draw the free body diagrams..and find what the acceleration is. Since they are both connected by a string, they will accelerate (different directions) with the same magnitudes.

    getting the free body diagram correct is essential
