Question
[6.]
A 20 kg box resting on a horizontal, frictionless surface is attached to a
8 kg weight by a thin, light wire that passes over a frictionless pulley. (See Figure.) The
pulley has the shape of a uniform disk (I = 1/mr²) of mass 4 kg and radius 0.3 m. After
the system is released, find (a) the acceleration of the box; (b) the tension in the wire on
both sides of the pulley; and (c) the horizontal and vertical components of the force the axle
exerts on the pulley.
