Two point-like beads which have the same mass are rotating at the ends of a li shown. The rod is initially rotating at w; = 2.00 rev/sec. An internal mechanism extends the length of the rod to be l = 120 cm. How fast is the rod rotating after its length was extended? (A) wp = 0.174 rev/s Wi (B) wr = 0.347 rev/s (C) wp = 0.417 rev/s (D) wp = 0.833 rev/s (E) ws = 1.67 rev/s (F) ws = 2.00 rev/s Rotation axis (G) wr = 11.5 rev/s A rotating massless rod with two beads on each end. The rod extends its length from l, to ly via an internal mechanism while rotating.

3. A rod with a mass of 10kg and a total length of 2 meters that can spin about an axis through its center ( I = ML2 ) receives a constant force of 5 N on one of its ends. As the rod spins, the 12 force will maintain the same strength and orientation i.e., angled at 60 degrees with respect to the rod. The rod is initially at rest. Total Length Axis 60 deg F, a. How many radians does the rod sweep through after a period of 10 seconds? b. What is the speed of a point on the end of the rod at that same moment?
