A uniform rod is 3.0 m long. The rod is pivoted about a horizontal, frictionless pin through one end. The rod is released from rest at an angle of 27 above the horizontal. What is the angular speed of the rod as it passes through the horizontal position?
 a. 3.0 rad/s
  b. 2.8 rad/s
  c. 2.1 rad/s
  d. 2.5 rad/s
  e. 3.4 rad/s

Question 2

A uniform rod (mass = 1.5 kg) is 2.0 m long. The rod is pivoted about a horizontal, frictionless pin through one end. The rod is released from rest in a horizontal position. What is the angular speed of the rod when the rod makes an angle of 30 with the horizontal? (The moment of inertia of the rod about the pin is 2.0 kgm2).
 a. 2.2 rad/s
  b. 3.6 rad/s
  c. 2.7 rad/s
  d. 3.1 rad/s
