The figure below shows a graph of angular velocity as a function of time for a car driving around a circular track. Through how many radians does the car travel in the first 10 minutes?
 
   


   
  a.
  30
   
  b.
  50
   
  c.
  70
   
  d.
  90
   
  e.
  100

Question 2

A uniform rod of mass M = 1.2 kg and length L = 0.80 m, lying on a frictionless horizontal plane, is free to pivot about a vertical axis through one end, as shown. The rotational inertia of the rod about this axis is given by (1/3)ML2. If a force (F = 5.0 N,  = 40) acts as shown, what is the resulting angular acceleration about the pivot point?
 
 
 
   
  a.
  16 rad/s2
   
  b.
  12 rad/s2
   
  c.
  14 rad/s2
   
  d.
  10 rad/s2
   
  e.
  33 rad/s2
