The rigid body shown is rotated about an axis perpendicular to the paper and through the point P. If M = 0.40 kg, a = 30 cm, and b = 50 cm, how much work is required to take the body from rest to an angular speed of 5.0 rad/s? Neglect the mass of the connecting rods and treat the masses as particles.
 
   


   
  a.
  2.9 J
   
  b.
  2.6 J
   
  c.
  3.1 J
   
  d.
  3.4 J
   
  e.
  1.6 J

Question 2

The rigid body shown rotates about an axis through its center of mass and perpendicular to the paper. If M = 2.0 kg and L = 80 cm, what is the kinetic energy of this object when its angular speed about this axis is equal to 5.0 rad/s? Neglect the mass of the connecting rod and treat the masses as particles.
 
   


   
  a.
  18 J
   
  b.
  15 J
   
  c.
  12 J
   
  d.
  23 J
