Homework Help: Crates on a Pulley Problem

  1. Sep 20, 2006 #1
    Two packing crates of masses m1 = 10.0 kg and m2 = 4.50 kg are connected by a light string that passes over a frictionless pulley as in the figure. The 4.50 kg crate lies on a smooth incline of angle 39.0°.

    a) Find the acceleration of the 4.50 kg crate.

    b) Find the tension in the string.

    See the figure at this link: http://www.webassign.net/sf/p4_26alt.gif

    I appreciate any input anyone can give me :wink:

    What are the forces acting on each crate?
    The sum of the forces is the product mass x acceleration.
