There is a fixed half cylinder of radius R on a horizontal table. A uniform rod of length 2Rleans against it as shown. At the instant shown,theta = 30^(@) and the right end of the rod is sliding with velocity v. (a) Calculate the angular speed of the rod at this instant. (b) Find the vertical component of the velocity of the centre of the rod at this instant.

1.	There is a fixed half cylinder of radius R on a horizontal table. A uniform rod of length 2Rleans against it as shown. At the instant shown,theta = 30^(@) and the right end of the rod is sliding with velocity v. (a) Calculate the angular speed of the rod at this instant. (b) Find the vertical component of the velocity of the centre of the rod at this instant.
Answer» Answer :(a) `OMEGA = (v)/(2 sqrt3R)` (B) `v_(y) = (v)/(4) (DARR)`
