A yo-yo has mass M 0.550 kg, axle radius R_(0) = 3.2 mm , and rotational inertia l = 3.4 xx 10^(-4) kg m^(2) about its rotation axis. Assume that the string has negligible mass and thickness. (a) What is the linear acceleration of the yo-yo as it rolls down the string from rest?

A uniform thin rod of length l is suspended from one of its ends and is rotated at f rotations per second. The rotational kinetic energy of the rod will be
A body is rotating with angular momentum L. If I is its moment of inertia about the axis of rotation is I, its kinetic energy of rotation is
Kinetic energy of rotation E and angular momentum L are related as
If the variation of rotational kinetic energy E with the angular momentum L of a body. The graph of log L and log E eill be in the form of
