A solid sphere is rolling down without slipping on an inclined plane of length 21 m with an acceleration of $5\,ms^{-2}$. The time taken by a circular disc to roll down without slipping to reach the bottom from the top of the same inclined plane is}

A solid sphere rolls down without slipping on an inclined plane of angle \(30^\circ\). If angle increases to \(45^\circ\), percentage increase in acceleration is nearly

A solid sphere of mass 2 kg and radius 50 cm is rotating about its diameter with an angular speed of $50 rad s^{-1}$. The angular momentum of the sphere is

A solid sphere of radius 18 cm is rolling down from rest from the top of an inclined plane of length 14 m and angle of inclination $30^\circ$. The time taken by the sphere to reach the bottom of the inclined plane is (Acceleration due to gravity = $10~\text{m s}^{-2}$)

A uniform circular disc of mass $\dfrac{\pi}{40}$ kg is rotating about an axis passing through its center and perpendicular to its plane with an angular speed of 150 rev/min. If the angular momentum of the disc is 6.25 Js, then its radius is:
