A uniform rod of length I is in equilibrium with help of two strings as shown. Just after string
on the right is cut, angular acceleration of rod is a, horizontal component (to the right) of
acceleration of center of mass is ax & vertical component (downward) is ay. Then,

A particle is rotating about a vertical axis in the horizontal plane such that the
angular velocity of the particle about the axis is constant and is equal to 1 rad/s.
Distance of the particle from axis is given by R = (Ro - Bt) where t stands for
time. The speed of the particle as a function of time is
R.
