The top edge of a rod of mass 2.80 kg is pivoted to a point on the ceiling. The rod is free to rotate about this pivot
and the length of the rod is 40.0 cm. The rod is pulled to the right until it makes 27.0 degree with the vertical and
then released from rest. At the same time a clay ball of mass 350 grams is moving to the right with a speed 160
cm/s. As soon as the rod reaches the vertical position (moving to the left), the clay ball hits the rod at the bottom and
sticks to it.
