A classical mechanics problem by Veer RanganClassical Mechanics Level 3
Two solid cylinders \(P\) and \(Q\) of same mass and same radius start rolling down a fixed inclined plane from the same height at the same time. Cylinder \(P\) has most of its mass concentrated near its surface, while \(Q\) has most of its mass concentrated near the axis. Which statement(s) is (are) correct ?
(A) Both cylinders \(P\) and \(Q\) reach the ground at the same time.
(B) Cylinder \(P\) has larger linear acceleration than cylinder \(Q\).
(C) Both cylinders reach the ground with same translational kinetic energy.
(D) Cylinder Q reaches the ground with larger angular speed.
