String is wrapped around an object of mass M= 0.5 kg and moment of inertia I= 0.02 kg·m2.
String is wrapped around an
object of mass M= 0.5 kg and moment of inertia I= 0.02
kg·m2. You pull the string with your hand straight up
with some constant force F such that the center of the object does
not move up or down, but the object spins faster and faster (see
the figure). This is like a yo-yo; nothing but the vertical string
touches the object. When your hand is a height y0= 0.24 m above the
floor,...

1. A rigid object with moment of inertia 0.4 kg mº is spinning with angular speed of 0.2 rad/s around a fixed axis. A constant torque of 0.6 Nm is applied that increases the rotation speed of the object (no other force is present). (i) Calculate the angular acceleration of the object. (ii) Calculate the angular speed of the object at t = 4 s. (iii) Calculate the angle spanned by the object from 0 s to 4 s.

One simple way to measure the moment of inertia of an irregular object is shown in the diagram. The object is mounted on a frictionless axis. A light string is wrapped around the object, passes over a light pulley (so it has negligible moment of inertia itself), and then connected to mass M = 40.6 kg. The system is released from rest. After mass M has fallen distance 4.05 m it is moving 2.67 m/s and the object has reached...
