[cnetterville]

Two blocks, m₁ = 1.0 kg and m₂ = 2.0 kg, are connected by a light string as shown in the figure. If the radius of the pulley is 1.0 m and its rotational inertia is 5.0 kgm², the acceleration of the system is
 
 
 
   
  a.
  (1/6)g
   
  b.
  (3/8)g
   
  c.
  (1/8)g
   
  d.
  (1/2)g
   
  e.
  (5/8)g

Question 2

In the figure, a 1.6-kg weight swings in a vertical circle at the end of a string having negligible weight. The string is 2 m long. If the weight is released with zero initial velocity from a horizontal position, its angular momentum (in kgm²/s) at the lowest point of its path relative to the center of the circle is approximately
 
   

   
  a.
  40
   
  b.
  10
   
  c.
  30
   
  d.
  20
   
  e.
  50
