A cubical block of side a is moving with velocity v on a horizontal smooth plane, as shown it hits a ridge at point O.
The angular speed of the block after it hits O is.
Ans. 3v/4a.

Given:
A cubical block of side a is moving with velocity v on a horizontal smooth plane, as shown it hits a ridge at point O.
To find:
Angular speed after hitting ridge O ?
Calculation:
