Alarge bell is hung from a wooden beam so it can swing back andforth with negligible friction. the center of mass of the bell is0.60 m below the pivot, the bell has mass 34.0 kg, and the momentof inertia of the bell about an axis at the pivot is 18.0 kgm2 . the clapper is a small, 1.8-kg mass attached to oneend of a slender rod that has length l and negligible mass. theother end of the rod is attached to the inside of the bell so itcan swing freely about the same axis as the bell. what should bethe length l of the clapper rod for the bell to ring silently, thatis, for the period of oscillation for the bell to equal that forthe clapper?

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
