A long thin rod is held horizontally. When released, it pivots around a fixed, frictionless axis through one end. Consider its angular speed when it is vertical? a) The final speed depends on the rod’s mass only. b) The final speed depends on the rod’s length only. c) The final speed depends on both the rod’s mass and length. d) The final speed depends on neither the rod’s mass nor length.

1. M, a solid cylinder (M=2.03kg, R=0.137m) pivots on a thin,
fixed, frictionless bearing. A string wrapped around the cylinder
pulls downward with a force F which equals the weight of a 0.670kg
mass, i.e., F = 6.573N. Calculate the angular acceleration of the
cylinder. (Answer in rad/s2.)
2. If instead of the force F an actual mass m = 0.670kg is hung
from the string, find the angular acceleration of the cylinder. Use
units of "rad/(s*s)

A uniform 0.030 kg rod of length 0.40 m rotates in a horizontal plane about a fixed vertical axis through its center. Two small rings, each with a mass of 0.020 kg can slide along the rod. They are initially held by catches at a position 0.050 m on either side of the rod’s center. The rod is rotationally accelerated to 30.0 rpm and then left to spin freely with no friction. While the rod is spinning, the catches are...
A thin uniform rod has a length of 0.550 m and is rotating in a circle on a frictionless table. The axis of rotation is perpendicular to the length of the rod at one end and is stationary.
A thin uniform rod has a length of 0.550 m and is rotating in a circle on a frictionless table. The axis of rotation is perpendicular to the length of the rod at one end and is stationary. The rod has an angular velocity of 0.42 rad/s and a moment of inertia about the axis of 2.60x10-3 kg .m2 . A bug initially standing on the rod at the axis of rotation decides to crawl out to the other end...
