A solid cylinder of mass `M` and radius `R` rolls down an inclined plane of height `h` without slipping. The speed of its centre when it reaches the bottom is.

Assertion: A solid cylinder of mass m and radius r rolls down an inclined plane of height H. The rotational kinetic energy of the cylinder when it reaches the bottom of the plane is mgH/3. Reason: The total energy of the cylinder remains constant throughout its motion.

A solid cylinder of mass M and radius R rolls down an inclined plane of height h. The angular velocity of the cylinder when it reaches the bottom of the plane will be :

A solid cylinder of mass 0.1 kg having radius 0.2m rolls down an inclined plane of height 0.6m without slipping. The linear velocity the cylinder at the bottom of the inclined plane is

A ring starts to roll down the inclined plane of height h without slipping . The velocity when it reaches the ground is

A metal disc of radius R and mass M freely rolls down from the top of an inclined plane of height h without slipping. The speed of its centre of mass on reaching the bottom of the inclined plane is
