A block slides down a plane. Inclined at `30^(@)` to the horizontal, with an acceleration a. A disc rolling without slipping down the same inclined plane would have an acceleration

Acceleration of a solid cylinder rolling without slipping down an incline of inclination theta is

An inclined plane makes an angle of 60^(@) with horizontal. A disc rolling down this inclined plane without slipping has a linear acceleration equal to

An inclined plane makes an angle of 60^(@) with horizontal. A disc rolling down this inclined plane without slipping has a linear acceleration equal to

It takes a block twice as long to slide down a plane incline at 45^(@) to the horizontal as it would take for it to slide down the same plane had the plane been frictionless. Colculate the coefficient of friction between block and inclined plane.

A sphere is rolling down a plane of inclination theta to the horizontal. The acceleration of its centre down the plane is

The acceleration of a solid cylinder rolling down an smooth inclined plane of inclination 30° is
