A solid cylinder of mass m and radius R rolls down an inclined plane of height 30m without slipping. The speed of its centre of mass when the cylinder reaches the bottom is [use g=10m/s^2 ]

Question

Accepted Answer

Correct answer: B. (b ) In rolling motion , V= 2 gh1+ I mr^2V= 2 10 301+ 12= 600 32=20m/s
