The pendulum consists of a slender 2-kg rod AB and 5-kg disk. It is released from rest
Chapter 19, Problem 19-44(choose chapter or problem)
The pendulum consists of a slender 2-kg rod AB and 5-kg disk. It is released from rest without rotating. When it falls 0.3 m, the end A strikes the hook S, which provides a permanent connection. Determine the angular velocity of the pendulum after it has rotated \(90^{\circ}\). Treat the pendulum’s weight during impact as a nonimpulsive force.

The pendulum consists of a slender 2-kg rod AB and 5-kg disk. It is released from rest without rotating. When it falls 0.3 m, the end A strikes the hook S, which provides a permanent connection. Determine the angular velocity of the pendulum after it has rotated \(90^{\circ}\). Treat the pendulum’s weight during impact as a nonimpulsive force.
ANSWER:
Step 1 of 6
For the first motion, applying the conservation of energy,
As the pendulum is released from rest,
