Two circular disks each with moment of inertia 11 and 12 are equal mass m are rotating about a horizontal frictionless axle through their centers with angular velocities w1 and w2.if the 2nd disk slip to the left and attached to the 1st one
find (a) The angular velocity after the attachment
(b)the ratio of the rational final KE to the initial KE

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
