Question

A cubical block of side 'a' 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 :-

$\frac{3 v}{4 a}$
$\frac{3 v}{2 a}$
$\frac{\sqrt{3}}{\sqrt{2} a}$
zero

The correct answer is: $fraction numerator 3 v over denominator 4 a end fraction$

In the figure shown a plank of mass m is lying at rest on a smooth horizontal surface. A disc of same mass m and radius r is rotated to an angular speed $omega subscript 0 end subscript$ and then gently placed on the plank. If we consider the plank and the disc as a system then frictional force between them is an internal force. Momentum of the system changes due to external force only. It is found that finally slipping cease, and 50% of total kinetic energy of the system is lost. Assume that plank is long enough. $mu$ is coefficient of friction between disc and plank. Distance moved by the plank from the placing of disc on the plank till the slipping ceases between disc and plank
