p9(1).png A 65.0 kg person stands a distance d = 2.5 m from one end of a uniform plank of mass 25.0 kg and length 8.0 m suspended by ropes at each end.  Determine the tension in the rope nearest to the person.

p1(4).png A simple pendulum consists of a point mass  oscillating on the end of a massless string of fixed length L under the influence of gravity.  Determine the angular acceleration of the simple pendulum shown for L = 1.50 m when the angle q = 35.00.

p1start(1).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 torque of 0.120 Nm is applied to accelerate the system.  Determine the acceleration of the system if the rod has a mass of 75.0 g.

Which is the most likely cause for this scenario: One screening cell of the AbSc was observed as 1+ at antihuman globulin phase, while the patient ABO type was identified as A Pos.

During donor testing, the sample was found positive for the antibody screen. How should the collection center proceed with the donated unit?

p8(2).png A uniform meter stick of mass 125 g has masses m1 = 50.0 g at the 0.0 cm and m3 = 250 g at the 100 cm position and balances when pivoted about the 70.0 cm position with the mass m2 at the 30.0 cm position.  What is the mass m2?

Determine the moment of inertia for a 1.8 m long uniform rod of mass 250 g pivoted about the center.

A 26.0 cm radius bicycle tire rolls without slipping across a surface with a speed of 12.0 m/s.  What is the angular speed of the tire?

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.

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.
