The rigid object shown is rotated about an axis perpendicular to the paper and through point P. The total kinetic energy of the object as it rotates is equal to 1.4 J. If M = 1.3 kg and L = 0.50 m, what is the angular velocity of the object? Neglect the mass of the connecting rods and treat the masses as particles.
 
   


   
  a.
  1.3 rad/s
   
  b.
  1.5 rad/s
   
  c.
  1.7 rad/s
   
  d.
  1.2 rad/s
   
  e.
  2.1 rad/s

Question 2

A mass m = 4.0 kg is connected, as shown, by a light cord to a mass M = 6.0 kg, which slides on a smooth horizontal surface. The pulley rotates about a frictionless axle and has a radius R = 0.12 m and a rotatinal inertia I = 0.090 kgm2. The cord does not slip on the pulley. What is the magnitude of the acceleration of m?
 
 
 
   
  a.
  2.4 m/s2
   
  b.
  2.8 m/s2
   
  c.
  3.2 m/s2
   
  d.
  4.2 m/s2
   
  e.
  1.7 m/s2
