p2(4).png A mass m = 60.0 g is fixed to the end of a rigid rod of length L = 40.0 cm pivoted about the other end.  A Force F = 1.50 N is applied to accelerate the system in the plane of rotation at an angle q = 20.00 with respect to the rod as shwon.  Consider rod to be massless and determine the angular acceleration of the system.

p14(2).png A mass m = 1.50 kg is connected to a string wrapped around a pulley of mass 4.00 kg and radius 75.0 cm as shown.  Treat the pulley as a uniform disk and determine the acceleration of the falling mass..  Consider the pulley to be frictionless and the string to be massless.

p3(1).png A 35.0 kg uniform plank of length L = 10.0 m is pivoted about one end and held level by a cable as shown.  A 75.0 kg worker stands 2.50 m from the pivot inspecting the plank.  What is the tension in the cable if it makes an angle q = 65.00 with respect to plank?
